180 BT and Retumbo, actually 6 shots after a bore clean and foul shot.
This group was with a full charge of Retumbo and 200gn AB, shots 1,2, & 3 went into the same hole and I pulled shot 4 and hung my head before looking down range at the target too see where I sent it.
I went out to break in the barrel and after 10 shots I tried some grouping at 100 yds. I think this barrel is off to a good start.
One of the four brass w/ the 200AB had a "crater" firing pin mark, no sticky bolts or any pressure signs other than the one crater. Is that something to worry about or should I back off a grain.
