[QUOTE="Tiny Tim, post: 3069084, member: 87887"] While I'm uncertain, without blowing out case taper, I don't think simply changing from the radiused shoulder to an "improved" shoulder would gain you enough case capacity to gain that much speed. That is a significant gain. Some cartridges gain that much by "AI-ing", but not all. Most add more freebore in the AI process and remove case taper, increasing case capacity in multiple areas. Weatherby already has a lot of freebore and about .020" body taper. The steeper shoulders also help with case stretch, but tend to "hide" pressure. Do as you wish, there is no wrong thing to do, just know that you may or may not get the desired velocity gain. Let us know what you decide. [/QUOTE]
