Whatever the change of velocity will depend on the burn rate for the powder you are using, which BTW, you haven't mentioned. With faster burners than W231 the difference will be pretty insignificant, but if you're using something from the medium-slow group like Silhouette, HS-6 or 3N37, you'll see a significant increase. I didn't mention Power Pistol because I don't use it because its got nasty muzzle flash. The powders I mentioned are spherical and will meter better anyway.
