Quick Review of Gallant Cast Bullets for 38/357

[JimGnitecki]

This is why using load data for the bullet is important... one could use modeling software to extrapolate much more data, but a starting load should get you there if it's the same material and bearing surface. .060 is a lot, and would probably be catastrophic in 9mm. The semi auto cartridges have much less wiggle room from the data and data runs I've done. Does that reduction keep you in Sammi minimums.

Yes, the SAAMI range for COAL for 357 Mag is 1.405 to 1.590. That bullet's crimping groove makes the actual COAL around 1.525", plus or minus a bit on each side due to cast bullet variances.

I THINK the reason this much of a reduction does not make a destructive peak pressure is because the powder load is so light.
