Muzzle Velocity data on pistol catrriges from short barrels.

[miko]

If I want to know what kind of MV difference there is between .357Mag in 2" vs 4" barrel, or between .357 and .38 from 2" and 4" and so on, is there data available anywhere?

Thanks,
Miko

Yah, I would also like to see 45ACP from a 4.25 vs a 5 inch barrel.
