OK I'm starting to learn something
but little enough.
I have been casting pistol 357, 10 mm, 45 acp, 44 mag for some years now.
I just bought the size ( caliber and weight) mold needed and went from there...maybe had to resize the 45 acp to fit in one of my tight chamber 1911s but thats OK. I started to reload for the 45/70.....naturally I get a .457 mold....but with plain base I get leading and keyholing at minimal velocities ( 340g bullet with 12gr Unique) . I am told to resize to a .459 of .460.
The problem is how do I do this with a .457 (actually .4575 cast ) bullet especially when I can only see .457 sizing dies from Lee. ( I did see speciality dies made by ? somebody in the states) but even if I got them I don't think they would or could make my .457 LARGER????
Does it help to cast with different alloy...more tin, linotype ???
Any help would be appreciated.
PS: The gun is very accurate with store bought ammo AND my reloads with MT Chambers .459 bullets
Thanks
