[QUOTE="J E Custom, post: 1761463, member: 2736"] I looked at this cartridge and realized that the WSSM could hold as much powder and cases were easy to get. I also talked to several smiths that had similar projects and they said the same thing that I had found out happened to them also. Velocity was not the issue. Twist rates, grove count and bullet quality was their main problem. I'm not trying to talk anyone out of anything Because I am one of the worst at trying something that Is considered impossible or impractical, just trying to warn anyone going down this road what's in store for them. The end results appear to be the bullets reach their limit, and accuracy is the final road block.It does no good to push a bullet to a high velocity and lose accuracy in the process. I had similar problems with a 7 mm that could push a 140 grain bullet at 3800+ ft/sec. If a person is lucky and chooses the right bullets, the right barrel twist and grove count, the right cartridge and powder combination, They might be lucky and have a winner. But there are so many variables, that only take just one to ruin the project, You have to ask your self is it worth it to spend all the time and money on a gamble. Some of us can remember when Weatherby did some velocity test for the government and both found them to be impractical. No matter how fast a projectile is pushed, it will always have drop/trajectory. so we compensate for it with drop calculations (And practice). Have fun and keep us posted on the outcome.
