100gr Nosler BT with 72gr H4831 at 3709fps and 100 yard 3 shot group covered with a dime from my Shilen 30" barrel 1 in 8 twist. 160gr Woodleigh with 71gr H570 same gun at 3095 fps. Haven't shot for accuracy with 73gr H570 3261fps but signs of pressure. Extractor mark and flattened primer but bolt still opens easy. I am guessing somewhere in between will be ideal for the 160gr bullet.
