45 colt.
well there is a can of worms
.what type of 45 colt A SQ ?.
ruger well .452 works.some of the revolvers from italy (clones) .454.colts lets break it down to pre war & post war.
pre war .454 was the norm and post war .452.that said some of the old cylinders are over sized and some under sized.I would take some cast bullets along with me(.451,.452 and .454) when I was looking at colts.pull the cylinders and drop the bullets into the cylinders and see what stuck.if a .454 hit the floor well that was a no go for me
.
if your thinking on a marlin 45/70 just make sure it has ballard rifling.the old micro groove barrels do fine with jacketed bullets but can be a pita to get cast to shoot well.you need fat bullets with a MG barrel.
.458 will work in the newer ballard rifled marlins.lee makes a mold a 340 gr lfn pb that was a great shooting bullet in my marlins.they would drop right at .459 and I would shoot as cast just tumble lube them with 2 heavy cotes of the liquid lube.
30.0 grs of AA5744 was a very accurate load and would make coyotes do some great back flips when smacked with one
.
if you need a hand or have question A SQ give me a call.
