[QUOTE="MontanaRifleman, post: 381356, member: 11717"] The longer out you seat your bullets, the more case capacity you will have and the less pressure you will get with the same charge of powder, everything else being equal. But the difference, in my experience, is very slight. However, once the bullet engages the lands, it may increase pressure. I would treat seating bullets to or into the lands as a new load to work up. In my Sako 85 300 WSM, when I seat the 210 Berger to the lands, the bearing surface of the bullet only catches about 2/3rds of the neck. With RL17, my velocity out of a 24 3/8" barrel is about 2935 fps. I would describe that as a "warm" load in my rifle. Definitely max. -Mark [/QUOTE]
