I've had good luck with the hanger bar on all my barrels.
I also make sure that certain barrels are mated to certain frames, get sighted in on those frames and always get shot on those frames.
I only have 1 in rifle config, all the rest are pistols.
7-30 Waters, 223, 256Win Mag, 45LC, 45-70, 243, 308, 6.5x284, 6BR.
I've shot them on paper, but that gets boring to me.
All of mine are plenty capable to hit clay birds at 300yds...some a little farther
The first thing I do to any frame is give it a good trigger job...then I start working on loads.
I haven't bedded any of my forends yet, I haven't felt the need.
Maybe this winter I'll do one and see if it makes a diffence.
