Glock 9mm OAL Help?

Glocktalk may have more recommendations for you, but my only suggestion would be to lengthen out your OAL quite a bit, even out to the max -- 9mm can go pretty far out and the longer you can go out (with reliable ignition) the narrower your feed angles will be.

What is getting caught where? Is a case rim getting caught on the ramp or is the front of the bullet doing it? Are you on the stock barrel or an aftermarket? Is the ramp polished at all?

I use RN and TC rather than JHP but I load them 1.130 to 1.140 for the glock.

I load to an O.A.L, of 1.155+- with 4 grs. Unique with a 147 gr bullet. Have used Rainier plated and Precision Delts jacketed. This load has worked well in all Glocks I've tried it in. Not a "Hot" load but it cycles the gun well and shoots well too. Got 3000 147 gr. MG bullets to try as soon as I get my present supply burnt up.

I load 115 XTP's to 1.115. I measured a factory Federal HP and it was shorter than that. Both feed in my G17, but then again everything does it is a Glock lol.

Yeah Kentucky that's exactly what I thought too. Makes me wonder if maybe 4.3 gr Bullseye is too light? Could this be the problem, or is it more likely the OAL of the cartridge?

Do they cycle ok racking the slide by hand?

4.3gr according to the Alliant "Reloading Guide" would indeed be a basement load since it gives 4.2 to 4.7 for Bullseye at 1.125" OAL. But then again the OP reports the mouth of the HP striking the feed ramp at the wrong angle.

We obviously have a problem with 2 big variables. You could get results by changing either willy-nilly, or you can get real answers by changing each (amount of powder and type of bullet) one at a time.

I will tell you that IMHO you've got the right OAL range since GoldDots load at 1.130". I can't say more since I've never used the MG hollow point, but have always intended to.

Hope this helps!

No one mentioned the condition of the magazine follower, condition of top metal insert on the magazine and magazine spring tension.

I have noticed that worn magazine follower, worn spring and/or damaged top metal insert on the magazine all affect the feed angle to the ramp, thus causing the round to jam against the ramp or chamber.

I reload my 115 loads to 1.12" - 1.124" OAL without any feeding problems. I never needed to polish the ramp on any of my Glocks (9/40/45) and polishing would remove the factory coating on the barrel.

Try a new/different Glock magazine and see if the problem is duplicated. If the feeding problem goes away with a different magazine, then the problem is with your magazine, not with your powder charge or OAL.

I hope this helps.

Dan,

If you ruled out the magazine issue, then looks like it's OAL and/or powder charge.

RFWobbly: Thanks for the advice I will try maybe some small batches of 4.5 and 4.7gr

5-10 of each and no more.... unless you want to get on a first name basis with your kinetic hammer.

Dan, have you tried your load in other Glocks?

I try to make my reloads so that it will "universally" chamber and cycle any gun - although if it works well in your gun, that should be a good start. I often test my reloads with as many of my friends' guns at the range to make sure they function well in all of them.

Many people complain that factory loads cycle well, but some are not as accurate. For ammunition manufacturers, reliability maybe more important than accuracy.

For me, I work to achieve the most accurate load using the particular bullet weight/powder burn rate/powder charge/primer/OAL to duplicate 5% sub/near factory performance for more consistent practice (I believe we fight as we train). I believe many manufacturer use faster burning powder so that their rounds will function well even in short barreled sub-compacts.

If I can do this using the most economical/cleanest burning powder/charge combination, great, but accuracy and performance trump economy and dictate which powder and charge to use.

Besides, if things really did get ugly, I want to be sure I can supply and arm my "friendly allies" with as many rounds as I can (I hope that never happens, but being prepared is what I believe in).
