Reeder Custom Guns - 401 Power Mag Load Data....

Some have expressed interest in the cartridge. Personally, it doesn't interest me. But, thought I'd share this old data from Handloader's Digest...

I see they are using faster powders than what we think of now as magnum pistol powders. I can see, if they used these with old case SWC, how they could lead up a bore. 2400 was as close as they had.

Where did that old can of Alcan go...
