Looks for Range

Looks for Range (1/11)

  1. never tumbled mags before, keen to see what the comments will be. Good question
  2. Firstly, Why do you want the 90 degree mount? What caliber are you running?
  3. yes i have seen that before in the mags... does that mean that the spring is binding at the bottom of the mag or something?
  4. Soo had an outdoor 8 stage shoot yesterday (very interesting), I have to say the reduced charge did help iron out some of the jams. I still had a failure to feed, although less frequent, and at one point all my rounds nose dived when i i had to start gun holstered and mags on belt. After that I cleaned the mags and for the last 3 stages i had no jams at all. It is now starting to seem that it could be the mags giving trouble and not the ammo anymore.
  5. I was running a really hot load, at one point the load was hotter than minor power factor. I think it is OAL that is messing me around. i was factoring at 4.4 gr, and i increased it to 4.7 gr. now i am lightening the load back to 4.4 gr
  6. I must say that i think the jams are most likely caused by the ammo. I have had the gun checked and the mags checked.i have corrected the mistakes i used to make and these were: 1) I was loading the rounds too short, 27.8 mm. I increased them to 28.5 mm then to 28.8 mm and now to 29.3mm. this definitely reduced jams. 2) I was crimping the bullet way too hard, now i just get rid of the belling. 3) The rounds were not factoring so i had to increase the powder to factor. 4) i was not removing the lube off the bullets after they went through the press, so the bullets were sticky.
  7. A stronger recoil impulse might aid some of the feeding problems. What velocity does your load produce? - last time i used a chrono the power factor I had was 125 power factor, can't remember the velocity. Is the gun new? Maybe it needs a little more break-in time for things to smooth out. - gun is not new, had it for nearly 3 years, 2 of which have been competitive years, and lots of rounds have been through the gun. You bullets sound like they are plated, correct? Any chance you can try some true FMJ bullets? Plated bullets are soft and can produce feed problems like you see. A hard FMJ bullet bounces off surfaces much better. - will give that a try. Although I will soon be using an STI Trubor in the open division and i will be using the same bullets. Does your feed ramp have rough spots? Has it been polished? - no it does not have rough spots. Do your nosedive-like jams only occur when the magazine is full? - yes they do, it seems that in between shooting stages if i keep the magazine loaded i tend to get jams, although not always. The mag takes 18 rounds but now i only put in 17
  8. Actually spoke to a guy today who sells me reloading gear, and i cant remember the make of sight . I will find out the name, but it comes with a plate already machined for standard 1911 dove tail slot (excuse sloppy terminology) and the brightness is manual.
  9. i almost never have any rounds that i need to remove when i drop the rounds into the chamber. ALL the rounds pass the plunk test. What i mean by not sitting properly is when i drop the rounds into the barrel and they do not seat properly i.e. sit flush in the chamber. They stick out. I only do this as an added precaution, all my rounds fit the chamber perfectly. I have measured, using a bore rod, what the max overall length for my gun would be, 31.7 mm. "You can't just measure a factory round, or any other, and use that as your guide for the correct OAL. That's not how it works". I know that you dont just use factory ammo OAL and reload with that. What i did was take some rounds loaded at 28.7 mm, 29 mm and 29.3 mm (i worked my length upto factory round length). I cycled these rounds through the gun and the smoothest, in my opinion, was the 29.3 mm OAL. the failure to feed jam that i get is very similar to this, note this is not my gun http://i55.tinypic.com/2lbls0m.jpg The second jam is a failure to extract http://i56.tinypic.com/wtsrrd.jpg(again not my gun) I also tend to get a Jam where the bullet does this http://s968.photobucket.com/user/kiin61/media/Mobile%20Uploads/image_zpse53d0b5a.jpg.html(not my gun) also, when you have a failure to feed, the gun is said to be 'out of battery', here is my reference http://www.northcarolinasportsman.com/details.php?id=485 The rounds i use are CMJ Restrike 9mmP 124gr RN.
  10. Not frame mounting a red dot because of the polymer frame. so I will only stick to the slide by machining a plate that slots into the rear sight slot.
  11. I am not sure how heavy the recoil spring but i will check. like i said the brass is sized just fine, especially after the plunk test i remove any rounds that do not sit properly or have difficulty sitting in the chamber. my rounds are at 29.3 mm OAL, the same as factory ammo, and the bought reloads i checked were 28.7 mm and they ran perfectly, so i think it is safe to say length is not the issue. Also i have shot factory ammo through the gun and it ran well. I am almost certain it has to do with excessive pressure, not that there are signs on the brass of such pressure, but i did experience primer flow when i shot the gun. As for the magazines i would think that if those were the problem then i would have more or less consistent jams on every stage, but i dont. some stages run smoothly and some turn into a jamming nightmare.
  12. Hey guys, I have a somewhat complicated issue to explain and try fix. The gun i am having trouble with is the BUL M5 Government 9mm. The barrel has 2 ports on the end (not strictly a compensator). In shooting IPSC obviously it is considered an open class gun because of such ports. I am continually getting jams in the gun, specifically failure to feed (out of battery) and failure to extract. I have eliminated certain elements that could cause the jams and these are: 1) I DON'T limp wrist. I know it is the first thing everyone asks when dealing with jams, dont ask me because i dont limp wrist. 2) My rounds do factor through a chrono for minor power factor. 3) my brass is thoroughly checked cleaned and i plunk test all the rounds. 4) according to every gun smith i have spoken to, my magazine springs, followers, base pads etc are all good. I also make sure they are clean. 5) gun is always clean and lubricated correctly. 6) My OAL is correct for the gun and all rounds cycle smoothly. I am reloading using s121 powder (fast burning) with a 124gr bullet. I have found a possible cause of the jams. This could be loading the rounds too hot? and causing the gun to cycle too fast. I found this out by shooting my reloads vs bought reloads. the bought reloads grouped extremely well where as my reloads were all over the place. This i figured out was because of too much pressure exiting the ports on the barrel causing the gun to move too much. I went back to my reloading data and found that i factored at 4.4 gr but i was actually putting in 4.7 gr due to increasing the length. what i have done is bring the powder down to 4.3gr and i will be shooting the rounds this weekend hopefully with no jams. What my question is, is it possible that a gun can jam when running too hot a load through it? i.e. the action closing too fast therefore causing a failure to feed and the action opening too fast that the extractor, in lay mans terms, looses grip of the brass casing to extract it?
  13. that is the bullet i currently use and it is very good
  14. One concern is, if i mount the serendipity to the slide, will the gun still cycle reliably with that extra weight on it?
  15. I would imagine there are lots of advantages to mounting the red dot on the frame rather than the slide??? there are, but the BUL M5 has a polymer frame, i asked Cmore and they said you cant drill and tap the polymer frame (obviously). So only option is the slide . not sure about lots of advantages though.
