GLOCK 17: 115gr vs 124gr vs 135gr vs 147gr 

Seems you got better as you went along, would be good to try the same drill with each weight in reverse to see if the groupings are similar.

Anyone notice he said 135 grain on two targets at the beginning lol. I use 124 sig v crowns edc

Good show, I'm always spreading the different grains of bullets in IDPA: 115 gr., 124., and 147gr. And always come back to 115 gr. for my Glock 34 gen 4, where the tightest groups are made. Thank you for your effort and demonstration.

147 was the best grouping, he was just high and left. Were these jacketed hollow points or fmj? Makes a huge difference.

Don't you love all the critique?? "what distance?, the target is moving, it's not scientific." I'm just glad you posted it.

Position of the target may have had some effect. Notice the upper left target all shots were high left. Lower left target 4 of the 5 shots were low left. A still unscientific but better approach might be to shoot one target with a bulls eye in the middle using a different target for each 5 shot group. Also be sure all 4 tests use the same brand of ammo.

That's really interesting. Was the barrel cold on the first set of shots (upper left) Thanks for posting this. Just starting to study the dynamics of variable ammo weights

I think the heavier loads work better in very small guns with short barrels but I like the 115 gr because it’s cheaper and easier to get. It looks to me like it shoots better out of your Glock too. Great vid!

I wonder which one had the best recoil for facilitating a follow-up shot?

Appears all 4 projectile weights yield equal fatal body cavity performance, i.e., tight grouping. From a self-defense perspective, the stopping power and how felt recoil affects target reacclimation would be metrics to consider..

Thank you for posting this review! I've just started seriously looking into to this matter. So far, the 115 and 124 appear to be about the same in terms of grouping.

From a point of view of a re-loader, unless you're using identical powder, primers, bullet manufacturer and grain weight, you would need several more tests. Even factory ammo does not have the same grain powder from cartridge to cartridge. Then, it also depends on what grain round was use at the factory to sight in the gun IF it was. Also, IF you sight in for 115g FMJ RN, then other weights could be different. I've found that hollow points fly worse then round nose and what good is carrying HP's if they're going to fly off target?

I mainly go with 124 +p but, I'm going to try some of those 115's in the near future. Never like any heavier than those two weights.

maybe i missed it but i was wondering,were these handloads, or factory ammo

Good vid.I made a video the other day shooting some bulk federal 115 grn FMJ's.And some Winchester 124 grn. Nato FMJ's @100 Yards on a Large man sized target.The 124 NATO round very noticeably out preformed the Federal 115's.The nato round is said to be near +P preasure.I dont know what the deal was but there are pistols that like Particular loads better than others.I have always heard that that the Glock 17 liked the 124's better than the 115's.One again great vid.

What was the Distance for them?? can you please let me know ..

I find heavier bullets hit higher than lighter bullets, especially at distances of 50-100'.

im gonna guess 124gr is going to be the most consistently accurate, the spacing between shots in the lower left is fairly tight, which is hardest for a right handed shooter

This looks like a 9mm group at 20 metres.what distance you shooting from?

factory or reloads?

124 gr is my guy.

You forgot to add at what distance you were shooting the different grain ammunition at

Did you even use a pistol rest?

what distance are you shooting from target?

Thanks for the vid buddy

Still ,...useful and informative, thanks for the video

Posting groupings without any referance to the distance at which it was shot is like giving a weather report with no location or time referance.

My 19 does better with the 115GR. 124 shot slightly low and left in mine.

obviously shooting the lower right quadrant target is easiest with most right handed shooter... To be fair without bias or any advantage the test should of been done with individual targets and not with targets divided in quadrant.

Would have helped if your target wasn’t swinging while shooting. Looked like it was 1” either way

Looks like the 147 jus high left i shoot my 147 with the tightest group also out of my g34

How many yards?

Good shooting

@avgguy47 distance?

Good job.

Heavier bullets tend to group higher, because they are leaving the muzzle a split second later, than the lighter bullets. In other words... The muzzle has rose a little bit higher from recoil, by the time that the heavy bullet has left for the target. You're welcome.

I shot the 115 grain much better than the 124 grain.... The 124 grain I shot went low and I put the 115 grain shots in bulls eye aiming both at center....

Freedom munitions 124gr HP FTW

Useless test, since your target is bobbing around every which way.

Did you notice any difference in recoil?

U didnt day 124 grain u said 135 twice

Honestly with large groups like that at such a close range you are not going to get very good data.

Between wind and not using a ransom rest this test means nothing.

147 g is a poor choice in the Glock 17. Because of the longer 4.5" barrel,than 9mm standard(4") heavy bullets will be less accurate and 115g bullets will be the most accurate . 124g will be close with this being the best choice weight for the Glock 19 and most pistols having a standard 9mm 4 inch barrel length. I have a S&W M&P Shield 9mm and with it's 3.1" barrel, heavy bullets like the 147g Speer Gold Dot and Federal HST 150 g will perform best. As a general rule ,specifically with 9 mm, with a short barrel heavy bullets are best. With a standard 9mm barrel about 4",124 -135 g bullets will perform best, although accuracy will be quite acceptable with 115 g bullets as well. With longer than standard 9mm barrels over 4", 115 g bullets will perform best with 124g bullets being acceptable.

EN TODOS LO MISMO..M

I would like to see this test repeated in gelatine.

I always shoot better with 124 or 115 it’s normal not even gun jus more recoil in for sure 147 anyone is tighter group with 115 n 124

Enjoyed it it’s meaningless but fun

Too much human error

LMFAOOOOOOOOOOOO

how far away?

i bet 124 gr for 9mm

9mm = 115 to 124 period, betwen 125 to 158 = 357 mag....

I think you just need to buys whatever the cheapest and learn how to shoot
