The forearm was removed again yesterday, and the head space adjusted a tad. Then the fore arm screw was tightened the same as it was the day before to 40 in-lbs. The first shots this morning, hit just about exactly where the shots hit yesterday. My belief is the loose fore arm screw had the rifle shooting to a different point of impact. Probably i should have checked the screw before i ever shot the rifle, but i didn't.

When one installs the QRBP, one just turns it in with fingers, until it stops. When the shooting is done, one just unscrews the plug with one's fingers.

These magnum rifle primers have been tested in sub-zero temperatures in more than one rifle, and ignition seems perfect. One Omega was left loaded, in the truck, for near exactly a month, and one sub-zero morning it fired without hesitation. Myself, i am not inclined to switch back to using shotgun primers. The one Omega plug modified to use rifle primers, i used in 4 different rifles, and results were always good. That plug has about 800 shots through it, if my memory is correct. The flash hole has never never eroded larger. From time to time i have used the rough part of the torch tip cleaner vigorously to remove carbon from the flash hole. This is something i would never ever do when using shotgun primers. Today, after 10 shots, the carbon in the flame channel of the QRBP, was removed by spinning a bare 1/8" drill in my finger tips. No way can one do that when using shotgun primers.

Time will tell, but at this time it seems what i need to do to have the rifle shooting consistent, to the same point of impact, is tighten the fore arm screw to the same in-lbs, each time.

This rifle will never get to go hunting anyway.
