I haven't posted in a year or so, but now I am back. I almost gave up on trying to get my 223 to shoot decently. I did the o-ring, latch was dry, hinge on the bag, and good follow thru. Still the cotton pikin thing would not shoot. Two days ago, I visited back here and realized I might need to relieve my barrel channel. I did and was astonished with the reults. Factory Win about 1.5 inch @ 100 yds. Now the bragging, my handloads using Accurate 2230 powder, Fed case, Win primer and bullet, right at an inch, with two touching!!
There is much valuable knowledge here!!
