[QUOTE="Gord0, post: 1524349, member: 99696"] I believe you just proved that a slower powder in a short barrel will give you more velocity. Run your H4831sc load up to 63k psi. At 59k you are almost matching the velocity of H4350. I think you eventually could get higher velocity with a faster powder, your barrel length would just need to be at an extremely short length. Going off my research of 1 (not really a quantifiable number, but all I've got). Running heavy bullets in my 300blk pistol at the highest attainable velocities. 150gr Speer gd BLK in a 7.5" pistol trying to achieve the highest velocity possible for a short range hunting cartridge. With H110 which is known for producing some of the highest velocities with lighter bullets I was able to reach 1775fps before pressuring out. Switching over to CFE BLK which is a much slower powder, I was able to achieve 1850fps before pressuring out. I burned a lot more CFE BLK to do it, (over 25% more) I have unburnt powder being thrown from the end of the muzzle, it's not nearly as efficient, but I obtain a higher velocity. [/QUOTE]
