375 in 454

[maddog2020]

got a 375 grain mold and what powder?
h108-h116- h110-2400 etc?
h108 is same as aa9
h-116 is wc680
any help?

Probly a powder quite a bit slower than WW680 or AA1680 (supposed to be the same powder). How's that biggie fit in your chamber(s)? Any room left for powder? This causes maybe a dilema as slower powder usually requires MORE powder too. Fun! Lossa fun!

any of the powders you listed will work. 2400 and maybe even 108 might be a bit fast for the extream top end but it doesnt do you much good to push cast bullets that fast anyway.

You'll be better served with the slower powders as they will create less chamber pressures resulting in a friendlier cast boolit load. With such a large boolit there won't be as much case volume which makes it easier to use the slower burners since they work best when the powder fills the case to nearly the base of the boolit or even slightly compressed in some situations. H110 will probably be the best powder as h116 will probably run out of case volume before you get enough in the case to create the pressures needed for it to work to its fullest potential. The powders quicker than H110 will go bang however will have more chamber pressures vs H110 if loaded to the velocities probably required to stabilize the large boolit for accuracy.

What kinda gun are you shooting, Maddog? Be careful that the base of the bullet doesn't bulge the case. I know that I can't get anything close to that weight in my Casull cylinder.
