i really like the mark v accumark. i picked up a 1998 lightly used 300 wby mag on gunbroker this past spring from a shop in Ga. then bedded the action from 1" in front of recoil lug to tang free floating the barrel. setup talley mounts and a 3-12x50 zeiss scope with 30mm main tube. otherwise a factory gun. she shoots great.
the attachment is from a 100 yd load work up from yesterday. this one seems to like the 178 amax over rl 25 or rl 22 with fed 215gm primer, wby brass collet neck sized, trim to 2.82". col is ~ 3.627". the factory weatherby 165 sp cartridges shoot well also.
