[QUOTE="DUCKMAN11, post: 2750607, member: 122313"] I think 140ish grains is going to be the "ceiling" on .257" bullets. Off the top of my head I can't think of a cartridge that could run a 160gr BETTER than a 130-140gr. The freebore needed to not eat up case capacity in any cartridge would be comical and would most certainly be single feed only in something like a 25-06 or 257wby. Maybe a WSM size case could run a 160gr in a long action. I'd think a 160gr .257 bullet would be close to 2" long or more. 1:7tw probably wouldn't stabilize a 160gr at lower elevations. Definitely not trying to knock the guy for trying new things and pushing the envelope.... just my thoughts. [/QUOTE]
