445 Super Mag and AA5744

[MtJerry]

I have come to love this powder and am using it with great results in my 45-70, and my 357 max (rifle).

My problem is that I want to use it in my 445 Super Mag (rifle) and can't find any data with it and a 250gr. bullet (Lyman 429244).

I can find data for a 265gr. bullet (jacketed), but not for cast bullets. Anyone willing to try and help me find a starting point?

It's awfully close to Dupont SR4759, a very popular cast bullet powder. IMR 4227 is right in that group, too. Find a starting load for one of those two powders and work it up to your satisfaction.

That's the info I was needing, Scrounger.

Thank you!

Scrounger;
Any load for a 265gr jacketed bullet would be safe with a 250gr cast bullet, Cast bullets are softer and cause less drag, there fore,the peak pessure will be less than the jacketed bullet, similar weights and same powder charges.
