'gwe,
The PM musta bounced. My bad,I must notta been counting. Laffin'!
I'd not throat an 8" twist .224" spout for RN's,you want it much shorter than that.
Hint.
Did gun a 7.7" Krieger this mornin',with W/W Virgins,I'm are fourty-[bleep] sixty-four,double hundo CCI's and a smooch with Bulk Blem 68 Me sooooo Horny HPBT's at 3250fps.
Odd you mention the 68 horns...one of my faves for longer range PDs in a std.223 with a 1 in 10 twist...should really perk in the 1 in 8 ( I have a few extras set aside....) However, they may not fit if I ream the throat for RNs....so I might go "Rogue" and not follow your advice...
just sayin'....
