So I picked up a "used" owner said never shot it and it actually looked never cycled there was no wear anywhere.

I have taken out two times and have just under 100 rds through it of US late 60s surplus, new manufactured ppu, and a few groups of hand loads that were set up for my buddies 700 42.5gr varget 175 smk. Everything posts 3in plus groups at 100yrds. I am not looking for the 1/4in groups my TRG shoots or the 1/2 groups my buddies 700 shoots but 3 moa plus for the MSG model is a bit out of line even my starndred Ruger 77 hunting rifle will better 1" groups with these rounds.
I am also noticing a ton of blow by on the spent brass (this is my first g3 pattern rifle and first ptr so I don't know if this is normal).

Any advice?? This firearm is no good and no where near worth the retail price if this is all it is capable of.
Thanks guys

Try handloading some different loads for it. Different guns like different bulet weights, powder charges, seating depth, shoulder bump, etc... Or try some factory match grade ammo in different weights. The perfect handload is the one that you built for your gun. It may take a while to dial it in just right.

What are you running for optics? How is your optic mounted? What type of rings? Are you doing your part?

Good to hear it sounds like the ammo as I have not made up a load for this gun yet. I will run some ladder tests and see if I can get anything it likes and I also have a few boxes of LC match I can run through it.
Weaver tactical on EGW rings on the ptr welded on mount. Doing my part except getting around to loading for it. Thank you for the response I just cant remember shooting anything that didn't care so much for 3 compleatly different loads although the only other auto loader I shoot is an ar15 that shoots anything well

Thank you

I do not know what your trigger is like. But, it may need a trip to Bill S. for a trigger job.

The triggers on these HK/Klones take getting used to, and might very well benefit from a trigger job by a pro.
The blow-by is because of the fluted chamber. Usually nasty almost bact to the rim. You should see the flute lines easily.
Good Luck finding your perfect load. Gun SHOULD probably shoot at least 1 moa.
HAPPY SHOOTING

First of all,if its got 1:12 twist;don,t bother with match weight bullets. They are not going to make a difference at 100yrds. If its got a 1:10 twist,then the match ammo should do well. try some 155gr Hornady TAP. Works awesome in my JLD wilson/TC barreld weapons. Yes,a billspring trig job will make a big difference.Remember,its the indian,not the arrow. LOL

These rifles are known not to shoot the heavy bullets well.

I've had good luck with 168 Federal match.

Whats the optics setup you have. H&K Irons at 100 probably won't get you to 1" groups.

The Msg91 is a 1:12. Try loading up some Nosler 155gr hpbt and some VV N-135 have had sub moa groups in mine.

The guys are right on the Bill Springfield trigger job, that's all I'll shoot in my 91 and clones. And they are right again with the bullet weight, the 1-12 twist barrels usually like 145-150 gr bullets, a AR-10 with a 1-10 twist will shoot the heavier stuff but then this is a HK forum. I just shot some of the new Privi-Partizen 145 gr BT-FMJ and it fed very well even in my PTR and grouped extremely well for military ammo. I wanted to see what the ammo and rifles were capable of and fired them from a lead sled to take the Indian out of the equation. The PTR-G.I. shot it sub MOA and my HK-91 shot (8rds)- 1/2 MOA. I just ordered a bunch of it. With that quality of rifle, when you get the ammo, they're right, under non-hunting, ideal, slow-fire conditions it will shoot 1-MOA. I just got the PWS- flash hider/ muzzle brake from HK-parts and could not believe how well it worked so I ordered them for the other rifles that did not have it yet. Reduced recoil a bunch over the older style PTR Brake and cut the flash in the scope out. I could not believe it would do both but it did. Adam was right again.

Hdy 168gr AMAX match is sub MOA in my F and my MSG. +1 to no 175gr bullets. Some guns with 1:12 will shoot them OK...most not so much. You should be fine with good 168gr, though. Also, check rings and optic.
