[QUOTE="LouBoyd, post: 946625, member: 9253"] Rules of thumb often to make other more important conditions happen. If the bullet engages and seals in the lands while the bullet shank still is still supported by the neck it should be OK. If the bullet is unsupported at both ends even briefly there will be blowby and likely poor accuracy. I'd be ok with .0180" shank seating depth if the jump to the lands is 0.0 to 0.04". I'd prefer that to having .257 seating depth and 0.11 jump to the lands. better would be to use bullets with a bit longer shank. [/QUOTE]
