Had two rifles rebored. Started with a 223 24" bull barrel. One a 257 Roberts the other a 6x47(222Rem Mag). A 7x57 would be good with a 24" barrel. Have the barrel turned down to .600" at the muzzle if you think the 24" bull barrel is to heavy for a hunting rifle.
Just make sure to tell the smith to do the turning down before the rebore. The H&R barrels are nort stress relieved and you end up with a tapered bore if the turijng down is done after the rebore.
Both my barrels were turned into octagon to remove weight. Both barrels shoot 3 shot groups under a 1/2".
Also they are both accurized as per my web site.
Shown is the 6x47. Rebored by Ron Smith in Wimborn Alberta.
