Roscoe hit the nail on the head as usual. I loaded 200 gr. Nosler partitions to 2800 FPS in my 300 wsm. I seated them as long as the Mag would allow. Even so the bullet was seated well into the case infringing on the powder capacity and causing a substantial bullet jump into the lands. with all that being said my factory Browning A-bolt would really shoot. I shot a few 1/2 Inch groups at 100, andone .6 group at 200 yds.It was so impressive thata buddy wanted it so bad that he paid double what it was worth.
