So Im a little confused about reloading campro 9mm 115gr rn ammo with titegroup.
I tried the following different loads to see what would work the best in my Glock 17 but i didnt notice any difference between loads.
4.0grs titegroup at 1.12 oal
4.6grs titegroup at 1.12
4.6grs titegroup at 1.10
4.4grs titegroup at 1.12
4.4grs titegroup at 1.12 no crimp

Does anyone know what im doing wrong or not doing wrong?
I don't have a chronograph so i cant really tell what is a better or worst load.

Any help would be appreciated.
 
Well i am getting some black powder burns on the cases.
Im was assuming that going from 4.0gr to 4.6grs the rounds would act and feel different when firing them. I also going to 4.6gr that the brass wouldn't have the burnt brass.
I want just a good base round for plinking and some accurate shooting.
 
Usually when you do a load survey like that, one load seems to be more accurate than another. That is true of most of my 9mms (over 20 of them.) But I have one pistol that is very accurate and seems to shoot the entire survey about the same.

Maybe you lucked into such a pistol.

Or maybe your shooting is not good enough to pick up on the minor changes in accuracy.

If you did not sandbag the gun at 25 yards, I suggest you repeat the test.

When I recover range brass I can always pick out the cases used with TiteGroup by the black stain. It is cosmetic. Ignore it. Pick the load that groups the best and is 100% reliable.
 
Thanks Ganderite for this information.
I will try doing the sand bag test with my reloads. I thought it would be noticeable shooting standing up but i guess not.
Ya im probably not the best shot with pistols to notice minor changes lol.
 
The campro copper plated ones should be used with lead data. 1.100 coal 3.9gr powder to 4.3gr powder in 115 gr bullet. Keep it around 1200fps or lower for best accuracy and light taper crimp if any at all.
 
The Campro website has load data on their Reloading page. They list 4.0 - 4.8 gr for that bullet so if you are not having any issues you could try bumping it up a bit. Ganderite is correct (of course) use a sandbag rest to take out as much shooter error as possible.
Good luck.
 
For me , the Glock was hard to tell the difference at 25 yards( rested)
But the CZ Shadow 2 was easy to pick a load for, much more accurate than the Glock.
And tight group is a bit dirty… but it’s cheap and usually plentiful.
 
Great comments above! I also use tite-group almost exclusively. Personally, comparing my Glock to other pistols I shoot the worse with it so my first response is to try another pistol :)

Tight-group is a bit dirty but as stated above it's purely cosmetic and cleans well in the tumbler. I'm using 4.4gr and am quite happy generally across many pistols
 
4.0 grains of WW231 with the Campro 124 RN bullet works very well. I might bump it up to 4.1 or 4.2 for a 115 grain bullet. TiteGroup is an amazing fast burning powder, faster than WW231. So at 4.0 TiteGroup with that 115 grain bullet, it should be target quality. I might go to 4.1 or 4.2 just because all mechanical powder measures In my experience will throw/meter lesser charges now & then. The one or two times your measure drops 3.8 or 3.9 is the time Murphy’s Law comes into play.
