Richard,
I have some 180 gr XTP-HP's loaded in .360 DW that will group a little over 1" at 100 yards. I shot a few 250 gr Beartooth LFNGC bullets that will shoot into 2" or less at 100 yards. I got this barrel in March or April and I think it's just now getting broken in. The groups may get better as time goes on and I shoot it more.
BTW, the same 250 gr bullets will shoot .69" at 50 yards in .357 brass with 7.5 gr IMR 800X.
