Thread: .44 Mag Crimping

What kind of grouping do you get with them? I've read it kind of goes to shit with the super heavies due to not having a fast enough twist.

I don't shoot them only have a 44/40 pistol they are to big for that, A mate uses them in an H&R with a 1:38" gets around an 1" groups at 50m.
bigest problem is the bore diameter they vary from .429" to .432" modern .44 mags have 1:20" twists and will handle 300 grain jacketed bullets
Cast bullets are short for their weight they don't have the jacket which is lighter than lead, also they are softer and reduce pressure with the same powder charge
and won't wear the barre.

How fast will you push one of your .30 / .303 cast gas checked 204grain boolits, and with what powder?

Best accuracy with cast is around the 1800-1900fps with the Alloy I use, If I source some antinomy and am super careful 3000fps
is possible it has been done in the US, But they are no good for hunting just like FMJ's straight through or shatter,
I prefer to make bullets for hunting much easier,
Powder choice is easy 2206H and 2208 start at 27.00 and work up just go for the best accuracy the HP's will expand at 900fps
the solids 1300fps,
