[QUOTE="Trickymissfit, post: 760536, member: 25383"] the last Remington 700 I bought shot a little over 4" for five shot groups. Shop said I was nuts and gave it them to try their hand with, and they couldn't get it better (I was using hand loads). So they let some benchrest shooters try their hand with it, and about two weeks later asked how I was able to get 4.25" groups out of it? The barrel was so rough it tore up patches! About that time I read how Bill Calfee checks out barrel blanks and did it to the 700 barrel. It had tight places and loose place all up and down the barrel. That's when I should have sent it back, but I'm hard headed as hell! Did a chamber case and I knew where to start! The chamber was .007" off center and angled at about 7 degrees going into the throat. The muzzel had a distinct bell mouth cut in it. I figured I could cut the bell mouth part out and shorten the big end a little but. The do a rechamber. Boy was I wrong! I ended up cutting about 1.75" off the bigh end, and 4" off the muzzel end. I finished out with a 20" barrel. Mr. Pindell loaned me a .223 N.M. chamber reamer that he was was a good one. I then take the reciever into work and recut the threads and trued it up to where it had about .001" compound error (the threads looked like pipe threads!).
