Qualifier needed for previous statement: 1:10 or 1:9 can shoot 100gr flat base or spire point style hunting bullets, but NOT 95+ weight VLD's. If you want to shoot 95gr and 105gr VLD's you need a 1:8 twist.
The 115gr bullets are really very specialized and need a 1:7.5 at least and probably a custom throat and magazine or single shot, which makes for a pretty dedicated rifle. Fine for competition, but probably not much else. I personally do not believe that one needs to go to 115gr bullets for hunting. Since competition is a narrow field, if thats what you have in mind you might be fine. I don't know of anyone who uses their dragster to get groceries either...
