    in USPSA Classifier Scores

    Posted · Edited by mstamper

    shot this one last night with my PCC.

    image.thumb.png.8c86b2e1b844c4c9eb54d39e20405940.png

     

    My best score and my highest placement in overall on that stage. YEAH!

     

    what made it even better was that the MD is not a big fan of PCC in pistol matches and when I finished he flipped me the bird (all in good fun) and then when he shot and did a reshoot, I still beat him. I jokingly told him it was Karma paying him back for flying the one finger salute. LOL

    Other than doing slide cuts to get a Shadow 2 or a Stock II to make weight, does it offer any advantage to making cuts on a pistol that's already legal? Like an SP-01.

    Outside of reducing weight, no. BUT there is the "that's cool" factor.

     

    I am sure that someone will say that the cuts cause air friction so that helps keep the muzzle from rising (LOL)

    Muzzle flip due to bcg travel?

    in Pistol Caliber Carbine

    Posted

    Here I was, HOPING, to get some sort of direction based on various shooters and hope to see a consensus of an opinion. The laughs on me. There has not been much of a consensus at all. 

    I have looked at the travel of my bolt. with the current setup (see above posts for my setup) the bolt is just past the BHO. I was sure it was moving more than that. I will be leaving the system as is for now. I might try a stiffer spring to get the bolt to move faster on the return to battery but there is not much I can do to get the bolt to physically be any closer to the breech face without completely forgoing the BHO mechanism. 

    USPSA Member Numbers

    in USPSA/IPSC Shooting

    Posted

    I had gotten my number back in 1983. Due to a bad decision on my part (married someone who did not like guns) I got out till last December 2017. I called USPSA and asked if they still had my number. I was very surprised to learn that they still had it in the records. My address had changed but they had my old ranking and my old RO info.

    I renewed and kept my old number, A25385

    I started shooting with my old club and I have learned that my number is one of the oldest there. LOL

    Hello: Testing is the only way to see what you like. I don't like the really short stroke in a blowback PCC. I find it harsh but it does reset the trigger quickly. I find my splits are just as quick and more accurate for me with the longer stroke and lighter weight of the buffer and spring. I have used a timer and hits on target to prove this to myself over and over again. For me a soft shooter is faster than a quick cycling PCC. This is what makes shooting PCC so much fun with all these different setups. Thanks, Eric

    Eric,

    I fully understand that testing is the only way to see what works for one person over another. I am looking for data that others have done and their impressions so that I can, at least, have a starting point for testing. I guess my ideal situation is a short stroke of the bcg AND a soft felt recoil. Is that a utopian ideal? that is why we buy gadgets and doodads and hand load to tweak our systems to find that ideal combination.

     

    Before I bought my blitzkrieg buffer system and spring I must have ready every post here about every buffer system and combination other shooters here tried. I made my decision based on my current bolt. The bolt in the diamondback pcc has a solid slug weight that extends on the end of the bolt. Other bolts have the weight inside of the bolt. I learned that the JP system needs a bolt that you can remove the weight slug to allow the bolt to travel properly with that system. I also chose the blitzkrieg because I did not want to deal with spending money on weight rings and the umpteen possible configurations that the jp buffer system had. I am happy with the blitzkrieg and 308 carbine spring even though I feel that the bolt is now moving a bit slower now. That, along with watching a youtube video about bolt travel having some effect on muzzle flip, is what started this thread.

     

    I did the same process before I bought my hiperfire 24 3g trigger to replace the mil spec trigger that came with the gun. Again, price dictated which hiperfire trigger I bought. I like flat blade triggers, I have an APEX flat trigger on my Q5 match. I just could not justify the additional cost to go from a curved trigger over the flat blade. 

     

    On another side, I see that you are in Alpharetta. I am in Peachtree Corners. Where do you shoot around town? I shoot the USPSA weekly match at Range Guns and Safes on pleasantdale road with the GPSL guys. I also shoot NAAS matches in Cumming at Bullseye up there. I shoot an occasional GADPA match at Norcross guns and range on PIB at Medlock Bridge road. I would love to find some more indoor USPSA matches till the weather improves. Do you shoot any outdoor matches? if so, where?

     

    Thanks,

    Mark

    Muzzle flip due to bcg travel?

    in Pistol Caliber Carbine

    The velocity of the bolt/buffer in the AR9 is dependent upon the pressure behind the bullet, or simply how hot your load is. The more powder used the stronger the push. Barrel length comes into play here, as well, allowing more time for that push before the bullet exits the barrel.
    If you want less recoil then reduce your load. Further tuning can then be accomplished by finding the best spring, or recoil system, that suits the load you have chosen. 
    To me the best load would be one that made a PF of 130. 
    I'm shooting a 16" barrel 9mm diamondback pcc with a birdcage on the front. I've put a blitzkrieg buffer system with a jp 308 carbine spring and a hiperfire 24 3g trigger and a burris ff3 optic.

    I shoot freedom munitions 124 grn plated rounds at 1061 fps at the muzzle of a 9mm pistol.

    The recoil is much lighter with the blitzkrieg system. I don't feel the buffer bottoming out. I still have some dot / muzzle movement that I'm not sure if it is from the round leaving the gun or from the bcg moving a lot.

    Muzzle flip due to bcg travel?

    in Pistol Caliber Carbine

    Posted

    Saw a video today that made me think about how much movement of the muzzle / dot is due to the bcg traveling farther than it needs to cycle the weapon over the actual bullet / gases exiting the weapon.

     

    I have read several posts here with users saying to put quarters or washers or even water hose gaskets to shorten the bcg travel.

     

    I'm wondering if the use of a buffer recoil system like the jp or the mbx or blitzkrieg is the best choice over just adding something to the end of buffer to control recoil?

     

    Or what about a combination of the buffer system AND reducing travel via stacking the end of the tube?

     

    I recently put the blitzkrieg system in my pc and have noticed a softer recoil but I am now noticing that it appears that the weapon is slower to reset the trigger.

     

    Would shortening the bcg travel to go just past the bolt lock allow the trigger to reset and the bcg return to battery quicker hence allowing for faster follow up shots and better controled recoil since the entire mass is moving less?

     

    If one does shorten the bcg travel, does a recoil buffer system even come into play or is all recoil then being handled by the buffer spring alone?

     

    Thanks,

    Mark

    POI changes ?

    in General Reloading

    Posted

    This is not a reloading question per se, but I am not sure where to put this.

    I currently use factory loaded 9mm from freedom munitions. remaned 124grn at 1081 fps at muzzle. I have used S & B as well and like it alot. (it has almost disappeared in the market for some reason)

     

    I shoot these out of my CO Walther ppq q5 match and out of my Diamondback 9mm pcc with a 16 in barrel.Freedom munitions

     

    I have a BURRIS FF3 8 MOA mounted 1.5 inches above the top of the picatinny rail zeroed in using a barrel laser at 25 yards on the pcc. IT shoots 2 inch groups at that distance.

    when I move the target in to 10 or 12 yards the POI drops 3 to 4 inches but still groups the same. I am obviously aiming at the same spot on the target yet there is this dramatic difference in the POI over the POA.

     

    I would have thought that the POI would have gone up the closer the target was to me. I am confused. 

     

    Can anyone explain what is happening?

    I hate having to slow down on a stage because I have to change my POA 4 inches higher to hit the zero down circle on targets in IDPA or the top of the A zone on metric USPSA targets to keep hits where they I want them to be.

     

    Would changing to a factory load that has a higher muzzle velocity keep the POI closer to the POA at closer distances?

    I know that the Seller & Bellot has a muzzle velocity of 1181 fps. This is really confusing me.

     

    Thanks for input.

    Threaded barrel & comp OR Mag-na-Porting for OPEN PPQ Q5 Match

    in Open Pistols

    Posted

     
    That is exactly what I was going to suggest.  Buy a non-ported barrel and drop it in.  You get to shoot Minor with no scoring penalty, and you get to use 140 mags fully loaded.  Three of my friends recently did exactly that.  One started with a ported Glock.  It had big, long factory ports.  He tried everything he could think of trying to make Major out of that gun.  We finally convinced him it was fruitless.  He bough a non-ported barrel and now shoots CO.
     
    Another friend loves his M&P.  He didn't like shooting Open Minor, so he dropped in a KKM non-ported barrel and is cleaning up the field in CO.
     
    I got into Open because of old eyes.  I have a fortune tied up in Open Major guns and mags, so I'm not going to switch.  If I were starting from scratch, I'd go CO.  Way cheaper and 95% of the fun.
    Until uspsa allows CO to use magwells and change out triggers I'm staying in open.

    I love the APEX trigger and my Taylor freelance magwell. And again, until uspsa modifies the provisional rules in the division to make it more like the limited division (where limited is basically open without compensators and optics), I'll stick to where I am.

    I just bought a pcc so, for now, the q5 stays in its current configuration. I might add a comp to later and might actually rechamber it to 9 major since Jarvis says their barrel will handle those loads.

    I don't know if the magnaporting will keep the muzzle flat, but it will help.  Here is an article that measured the effect of porting on muzzle rise in a Glock 19C:   http://www.shootingtimes.com/gunsmithing/recoil-reduction-ports-vs-compensator/

     

    With the Lone Wolf 2 hole comp, you might have to use ammo with a reasonably strong recoil impulse to get the gun to cycle, according to Lone Wolf.

     

    Something to think about:  Ask Jarvis if their Walther barrels will handle 9 Major.  If they have enough chamber support, they should do fine. You can buy 9 Major factory ammo from a couple of ammo manufacturers, if desired. This, along with a better compensator, would allow you to shoot Major in Open, if you decide to go that route. But knowing if the Jarvis barrel will handle 9 Major is good information to have even if you don't decide to take advantage of it.

     

    I did not think about asking about if the Jarvis barrel will handle 9 major. Thanks for that idea! There is another user on the walther forums that uses the 2 port comp and put a 13# spring on it and it runs fine. I will message Jarvis.

    I magna-ported a 5 inch M&P several years ago. It wasn’t worth the effort or expense. I am sure Magna porting would be valuable in some pistol hunting applications with much larger calibers.

    Regardless of what you do, you will be at a disadvantage in shooting open minor. And due to that fact, I wouldn’t do any of it.

    Good luck to you!

    I love to shoot. While I am competitive, I know that I will not be able to compete against the 38 super or 38 super comp or even 10mm / .40 cal guys on any given day with a perfect running gun. THAT being said, I have out shot other open shooters due to the overall reliability of my Q5. I have seen lots of FTF, light hammer strikes, and various jams on full on RACE guns that allows me to move ahead by being consistent.

     

    The main reason I am shooting open minor is that my older eyes just can't see the IRON sights as well any more, so to be able to see I added a MRDS, that, along with the other modifications put me in OPEN class. I am ok with the division. I honestly think I can be a solid middle B shooter as the gun sits. I think I can get to a high B with comping the gun ( I am a middle C now but only have 4 qualifiers so far after being out of the game for 20 years)

    Threaded barrel & comp OR Mag-na-Porting for OPEN PPQ Q5 Match

    in Open Pistols

    Posted

    I am going round and round in my head as to what to do.

    I use my Q5 shooting minor / open in USPSA indoor matches (till the weather warms up). 
    My specs on the gun are 9mm, SS guide rod w/ 13# wilson combat flat spring, APEX flat trigger, Burris FF3 MRDS, Trigger lightened to 3.25#'s, TF magwell and mag extenders. I am wanting to take it to the next level to run it in OPEN class and that would be to compensate the barrel somehow.

    The Q5 has slide ports in it already and Mag-Na-Port will enlarge the top ports on the slide next to the front sight for about 160 plus shipping. I have to send off the gun to them and will be without for several weeks or more.

    I can order a Jarvis threaded drop in barrel and a Lone Wolf 2 top hole compensator for about 320.00 plus shipping and put it together myself.

    Both are good solutions. the Mag-n-port will allow me to continue to use my current holster but I am wondering if there will be enough gas blown out to keep the muzzle flat. 

    The Jarvis/Lone wolf combination will keep the muzzle flat from what I have read BUT, due to the compensator being wider than the slide I would have to purchase a new holster costing about another 175.00 average price to allow for the width of the comp (unless the sides of the comp could be ground / milled down to be as wide as the slide)

    I am interested in learning from those who have ported or comped their Q5 AND shoot competition what your pros and cons are for each.

    I am NOT going to be changing my loads to shoot 9mm MAJOR as I have read too many horror stories of stock barrels not being able to survive shooting major PF and I don't want to buy a custom barrel nor do I hand load.
