45 Colt/300+/1.600?

[Naphtali]

Where might I find reloading data using 300-grain bullets and heavier for 45 Colt cartridge with overall length of 1.600 inches?

I describe characteristics of/for a Freedom Arms M97. Freedom Arms reports the M97 accepts Blackhawk pressures so long as cartridge OAL does not exceed 1.600 inches.

Are there available any off-the-shelf 300+-grain bullet molds that drop WFN bullets with crimp-to-nose length appropriate for 1.600 OAL?

The standard Lee C452-300-RF will work when crimped to the top crimp groove.
The Hornady 300gr XTP also fits when crimped in the top crimp groove.

Use full case of RL7 or WW680, around 25 and 28 grains respectively with a 300 plus grainer. Do not compress those very small granules. ... felix
