[QUOTE="BryanLitz, post: 715164, member: 7848"] 3000 for a 230 corresponds to more like 3100 with the 215. Gre-Tan ([url=http://www.gretanrifles.com/]Gre'-Tan Rifles[/url]) smithed one of the rifles I worked on, and I think the other was by Surgeon. Both very well put-together. The throat length is the only real thing to focus on getting right, that and the 1:10" twist. No magic with the 24" or 26" length. Same trade-offs apply: longer barrels produce higher MV, but have more harmonics and need to be stiffer/heavier. Shorter barrels make more practical hunting rifles, etc. Cool thing about the .300 Norma is you can get 'enough' velocity with a short barrel. [/QUOTE]
