9mm Bullet weight? - The Firearms Forum

Ron01013 · 01-12-2012, 02:16 PM

Loading 115gr and have heard I'm better off using 124gr.
why the differance?
I shoot and load for fun, paper, jugs ect:
Thanks for any info,
Ron

Don't know, all I've ever load are 115 grain.

I switched because some of my 9mm pistols and those of some of the other Old Guys were hitting below the point of aim. JLA one of the local forum experts suggested that I move up to the 124 grain from 115 as it would probably print higher. He was 100% right and they now hit at point of aim. For serious social work I am loaded with 147 gr.

Shoot what works best for you and your gun(s). I have read that there have been some 115 issues related to function when used in Glocks and Glocks with aftermarket barrels, but not a reason not to use them if they work for you. I find that in my carry weapon 147 gr bullets function fine and are more accurate than lighter bullets I've used--but that's me...

the 115s will make good paper punchers and beer can busters. They are cheap too.

Only time youd be 'better off' is if you have a POI/POA discrepancy (only an issue with fixed sights) or for some odd reason your iron just dont like 115s.

I personally prefer 124 gr in the 9mm Luger. I find them a bit more accurate than the 115s and the 147s

Yep, the 115's are less expensive but the 124's typically perform a touch better from my G17 and XD. The difference is subtle, but my pet load is a 124 over Power Pistol.

Dirtypacman · 01-13-2012, 12:32 PM

Think I will give the 124's a chance. Thanks for the information very helpful.

Ron01013 · 01-13-2012, 12:50 PM

Thanks for all the info...will try the 124's
My 92fs is shooting below POM with 115's
My load is 4.6grs of Bullseye...is the a better powder to uae????

JLA · 01-13-2012, 08:25 PM

Bullseye is a good powder for the 9. Thye 124s will have a bit higher POI than the 115s

Regular Joe · 01-14-2012, 11:04 PM

Bullseye can't reach full power in any 9mm load, except lead or plated bullets, which aren't loaded to full power for the cartridge. Pressure runs VERY high for the velocity attained. For 115 gr. jhp bullets, I prefer HS-6, and my standard load is a 124 gr. jhp with lotsa' Blue Dot. Both of these powders reach the highest power obtainable from the caliber without running terrible pressure. If popping jugs and the like is your game, hot HP's are the ticket!

Interesting...I got an xdm this week and the only ammo i have for it is the cheap stuff from wally world - 115g and it does hit low.

I've been reading up on reloading and bullet length to barrel rifling twist rate is critical for good accuracy. The formula for figuring this was thought up by greenhill in 1879.
Read more here (about 2/3 down the page) http://en.wikipedia.org/wiki/Rifling
and here's a calculator for ya http://kwk.us/twist.html

Heaver bullets are of course longer.

Try a box of speer lawman 124 gr in that XDm prof. Im bettn theyll rag out a nice golfball sized hole at POA in a 25 yd target.

Mike Venturino has a nice article "Point of Aim Vs. Point of Impact" in the the March/April 2012 issue of American Handgunner.

I get to read this fine magazine thanks to a TFF giveaway. Thank you TFF.
