What COL for LEE C452-300-RF 45 Colt

[corvette8n]

I just ordered the Lee C452-300-RF 2 banger mold and want to use this boolit in my Puma M92 in .45 Colt. I don't have much load data for this boolit. Any help would be appreciated. I already had 1000 gc on hand. I don't mind stout loads as this is the only firearm I own in .45 Colt, and I think this rifle can handle it ok.

I think you will have to crimp in the forward groove for that round to function in your rifle. I had to do that with the Marlin I had. My Ruger Blackhawk would let me crimp in the rear groove.

My Puma M92 will feed the Lee 300 grain slug crimped in the lower groove. I had a different problem with it as the bullets were not striking point on at 50 yards. Velocity was just a tad under 1000fps. Metal butt plate, light rifle and these slugs makes for a tender shoulder after 20 or so shots.
