RE: Need Help with CVA
Wht is not very well, 4" groups at 100, or 12" groups?
If it is shooting well enough to hunt with, I'd just hunt this year and worry about trying to fing a more accurate load for next year.
If the thing won't hit the side of a barn from the inside, you probably have scope issues (if you have a scope) or the gun just does not like that bullet. If you have a scope and iron sights, take the scope off and shoot the irons as a test. If it groups you know it is the scope.
If it is not the scope, try another bullet and drop the charge a little. Work up from say 80 grains.
