Inaccurate Yugo M48

Get bigger backer with no holes, shoot rifle from a rest not offhand. That is the only way to find what is going on for sure.

I am putting my money on a brand new big time FLINCH.

The cure is to get a chicken pad 1/2" thick to wear (past recoil shield) and use ear plugs and hearing guards. In 500-1000 rounds it will go away. (Hopefully) your shooting will become much more comfortable that way.

But one day, I decided to stick a dial caliper in the muzzle and measure the distance between grooves. The groove distance should have been .323 (please forgive if my memory is faulty)but instead it was .327". I had a brand new Big barrel!! Since I was shooting standard 8mm ammunition, I was hosed. The only way to tighten the groups was to get a tighter barrel. And I ain't planning on doing that.

I don't own a single 8mm with a .323" groove diameter, the tightest one I own is at .324 and the loosest is at .326" Yours is a bit looser

One way to combat this problem is to use bullets with long bearing surfaces. The bullets should swage up in the bore, but if the bearing surface is too short, the bullet is likely to exit the bore canted. One bullet that works really well and is often overlooked is the 170 gr Hornady round nosed bullet. True, it has limited range due to it lack of aerodynamics, but I've shot it very successfully out of all of my 8mms to 200 yards, which is probably as far as most people will ever shoot these rifles anyhow. Sierra matchkings also have very long bearing surfaces and might be worth looking at, but I haven't tried them because I'm not interested in paying that much money for bullets to shoot in a 'plinking' gun.
