Just picked up a ptr msg91 - groups suck any advice

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

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
