[QUOTE="cummin_un_glued, post: 878770, member: 28533"] powder to bore to projectile weight and bearing surface I would think would be a much larger factor then simply the barrel length. sure if you are using a very slow powder in a short barrel then you can set up such a scenario but I belief your examples to be more the exception then the rule. i'm not building a 30 cal or a quarter bore and the barrel length is decided so the main question here is how much of what powder is it going to take to push the 165gr .277 bullet to 3200fps. if we could figure that out that would tell us what case capacity is needed therefor what parent case to use.
