Ok-quick and silly test here. Loosen all action screws. Real lose.now try to chamber a round. The trigger gaurd you got?. How does it compare in thickness to the stock one. What is your case length?. Are the cases being reloaded ones that where shot in your rifle?. As one other posted,Take one of your cases that has been resized and try to chamber it with out bullet in it. SIlly as it seems,,If the primer is not seated deep enough this will also cause your bolt to not close.
