The groups fired without the forearm, what do they tell you. The first one, the shots are all over the place and the second one has horizontal stringing. Neither one is any good. If the rifle does not shoot with the forearm on then you should go through the accurizing program I have laid out in detail in the FAQ's.
Checking the rifle without the forearm is a waste of time and ammo, since the rifle is never used in that mode. As in the above groups it is totally inconclusive.
Same as checking a rifle on the bench with support under the hinge pin, nobody ever shoots like that in the field.
