    I've loaded nothing but 115 grain FMJ's for my G17 and G34. Before I order another 1k, I thought I ask the group if 124 gr FMJ work better for Glock factory barrels. I'm shooting targets and USPSA.

    Thanks in advance.

    Depends on the gun and what you want to do with it. One of the best jacketed bullets today is Montana Gold. USPSA is all about an accurate PF load then mastering your weapon. Heavy bullets with fast powders will give less recoil than lighter bullets.

  3. I like 147-grain bullets in 9mm. Being subsonic, they lack the harsh supersonic crack of light-weight bullets. The subsonic 147s also can provide audible feedback on steel targets. My current competition choice in 9mm is the Montana Gold 147 CMJ bullet over 3.6 grains of Bullseye with a Federal primer and COL of 1.13.

    Another +1 to 147gr bullets. I haven't reloaded them, but my Glock's love factory 147gr loadings.

    Also, I don't even worry with 115gr anymore. I reload 124gr, and that's all I shoot now, until I get some 147gr bullets to load up.

    You won't have any trouble shooting 115s, 124s, 147s, or any of the other possible combinations. I say that, as plenty of people shoot factory stuff from Walmart, mostly 115s with no issues. Many in here shoot 124s or 147s. I also prefer a 147 loaded to around 915fps out of my G17. A little faster is okay too.

    Montana Golds are great bullets, but the Precision Deltas are just as good and a little cheaper. Only thing is... MG is never out of stock on those, and PD quite often is.

    Thanks for the advice all. I'm going to try 124 grain for my next bulk purchase. I like the idea of 147's and the reduced noise due to its subsonic velocity. I plan to try a 100 of those for evaluation too.

    I would get a few hundred of each weight and see how they shoot in your gun.

    while the differences are miniscule and not likely to matter in combat style guns shooting ipsc/idpa and similar type targets of generous size, I've found since the standard european bullet weight for a 9 is 124,and since most 9mm guns are designed and/or built in europe, that most of my 9mm's shoot best with some sort of 124 grain ammo. Having said that the exception has been my glock 19. prior to this years GSSF season I had a good tail chasing episode at the range testing all bullet weights and styles I could to find the most accurate. at 25 yards the difference in group size using 10 shot groups from best to worst was under 1 inch. On gssf or ipsc targets that is never going to be the difference between a hit or miss,or getting the round in the a zone. after expecting some type of 124 grain to shoot best (as has been the case in a dozen or so other 9's I've owned) the one that shot best out of my 19 (again by just a hair) was lowly CCI Blazer 115GR.
