    Bar Sto Barrel 9mm 115 gr OAL Question

    in 9mm/38 Caliber

    Posted

    Thanks for everyones help.  Tested 3 new loads today and have found one that runs perfectly, no FTF, light primer strikes, or FTEs.  I needed to up the powder to 4.0 grs of Titegroup and shorten the OAL to 1.130.  Now to make some rounds, check the sight in, and run them through the chrono.  Thanks again.

     

    Bar Sto Barrel 9mm 115 gr OAL Question

    Additional Information

    Just had a BarSto ported barrel fit into my Springfield XDM by a professional gunsmith.  He tested it with factory 124 gr ammo and worked fine.  I got it home and tested it with my 9mm load that I have used for many years and am getting failure to feed issues. (See photo).  My normal load is 3.8 grs Titegroup with Rocky Mountain Reloading 9mm 115 gr FMJ round nose bullets (chrono 1050 fps).  OAL is 1.140.  Question......is OAL too long that would be causing these misfeeds?  The Bar Sto barrel chamber is tight with drop ins but the rounds do fit into chamber.  Just not when being stripped from magazine.  Any suggestions appreciated.  Or, could stretching the mag spring just a hair to increase upward pressure help solve the problem?  Or......do I need to increase powder charge to make sure slide travels far enough back to fully compress recoil spring?  If yes, then who has a load for my bullet and powder combination that will get me the 1100-1150 fps I would need?

    Does this only happen when your grandson shoots the gun ?

     Or does it happen to you also?

    It has happened to me too, and I shot USPSA for 20+ years so I know it's not limp wristing.  I have bumped the fps up and am awaiting an 11# spring.  Should solve the problem.  Thanks.

    Eric is very correct above.  IF you decide to go lighter on the Recoil Spring, please ensure that you use a Reduced Power Firing Pin Spring also.  There is a fine balancing act in the relationship between those to springs, as they work in opposite directions on the same plane.  If you don't change the FP Spring, then slide can be pulled out-of-battery during the trigger press or the slide's closing could be retarded to the point where the slide won't close.  Somewhere between 13# and 11 is where that really can start to show itself.

    I should have mentioned that I have installed a Charlie Vanek trigger kit in it and installed the 4# firing pin spring, so I got that part covered.  Doing some testing today and, if need be, will order the 11# recoil spring.  Appreciate all the great answers.   Thanks.

    Hello: when my son was 8 we had some issues with a Glock 34 that would not cycle sub minor loads. I ended up with 136PF loads with 115's for him. I used a 13lb ISMI recoil spring in a Gen 3. On the Gen 5 G17 try a 11lb ISMI recoil spring and see how that goes. Use a lighter striker spring as well. My load was 4.1gr Tite Group, 115 plated bullets, 1.140" OAL and Federal primers. The kids can handle the recoil just fine if they grip it and rip it. Thanks, Eric

    My concern is, with an 11# spring, are you risking damage due to increased speed of slide?

    Not trying to be critical of the photography, but it's just off-angle enough for me to not be able to say authoritatively, but...

     

    It appears that the slide is not coming back far enough to actually get BEHIND the case head to push it into the chamber.  If it doesn't, the stripper rail can actually "friction" the round out from under the magazine lips and start it towards the chamber.  Once the nose of the bullet hits the feedramp, all heck breaks loose and the base of the cartridge pushes down to go under the stripper rail.  In the military, that's called a "Bolt Over-ride". 

     

    That is often caused by too much Recoil Spring, not enough power in the ammo, or not enough resistance to recoil being offered by the shooter (the infamous "limp wrist" malfunction).

     

    13# sounds right for IPSC Minor loads, but your Ammo seems on the low side (actually sub-Minor at a 116 Power Factor).  Hodgdon recommends weights in the mid-4 grain range with jacketed 115s and TiteGroup.  Combine soft ammo with a 70 pound grandson and we have a perfect formula for this to occur, especially if his recoil-control skills are not perfect ("leaning back" stance, etc.)

    Thanks!  Will make adjustment and go to range tomorrow.

    I have a Gen 5 Glock 17 that I am reloading for on a Dillon 550 (reloading experience 20+ years).  Right now it has a 13# recoil spring in it (17# factory too hard for grandson to pull back).  Load right now is 3.8 grs Titegroup with Zero 115 gr. jacketed roundnose bullet.  OAL is 1.070 and they chrono at 1002.60 average.  But, every now and then I get a FTF as in attached photo.  So, what causes this?  Too short OAL?  Recoil spring weight?  Powder charge?  Suggestions appreciated.

    Gen 5 Glock 17 Recoil Spring Question

    in Glock

    Update

    The standard Gen 5 captured 9mm guide rod/spring unit is 16 or 17 lbs, I believe.  Am I correct?  Does anyone make a unit for this Gen 5 that is 14 lbs? Where purchase?  Link?   I reload and am looking for a lighter recoil spring assembly.  Not using any +P ammo in it.  Thanks for any help.

    Adjustable Sight Set Recommendations

    in Glock

    Posted · Edited by nhglyn

    Just got a Glock 17 ( I have had numerous Glocks before) and I would like to get an adjustable sight set for it.  I like a plain serrated black rear and a red fiber optic front.  Can anyone recommend a set that fits those criteria?  Gen 5.  Front sight is not in a dovetail, it has that heaxagon shaped "pin?" inside the slide.

    Ruger Mark IV 22/45 Lite Ammo

    I have a Ruger Mark IV 22/45 Lite that I have upgraded with Tandemkross parts.  Have added their TK compensator, Halo charging ring, Volquartzen trigger kit, TK trigger, TK extractor etc.   Gun shoots great but seems finicky about what ammo it likes.  Tried CCI standard velocity and was getting a number of fail to extracts.  Figured it was the extra weight of the Halo on the bolt slowing things down so switched to Federal high velocity.  Works better with fewer FTE's but getting some failure to fires.  What should I try next to make this 100%?  Was thinking about trying CCI MIni Mag, anything else that is not ridiculously expensive?  Thanks for any suggestions.

    So, I added a Tandemkross "halo" slide pull to this gun and have had a few failure to extracts since installed.  I assume it is because the extra weight is slowing down the bolt.  Should I just switch to high velocity ammo to solve the problem?  Thanks for any help.

    Ruger 10/22 Bipod Suggestions

    in Gear & Accessories

    Posted

    I have an older Ruger 10/22 that I would like to get a bipod for.  It has no sling swivel to attach one to, see photos.  Can anyone suggest a reasonably priced bipod that would fit on this rifle?  Something that would just take the place of the barrel band?  Where purchase?  Thanks in advance.
