crimped on hornady gas checks do giv more accurate loads [/blockquote]
Mmm...maybe 'cause it's a better seal and leads less??
Wewouldn't want that in .45LC +P loadswould we......
Has nothing to do with leading but more to do with making a nice square base- the same thing you get with pistol bullets without gaschecks.
So a GC on those 9mm bullets to fend a poor seal wouldn't have helped.....interesting. Whyo WAS talking about "hard cast", which is typically quite, how would you put it.....HARD.
Nope, gaschecks would simply treating a symptom and not the disease. Too hard = leading.
I run hard cast GC'd in my LC to facilitate maximum penetration via maximum velocityfor which the bullets purpose denotes....which is likely bustin' through a lot of bone structure before it reaches anything gooey should the need for a sidearm arise. For such needs I'd not even consider soft lead....and I'm guessin' Whyo wouldn't either.
Something as hard as W/Ws is plenty hard to bust bones, and it will expand a bit to boot.
Now that right there is some funny stuff. Anyone with a lick of casting sense knows a slugged barrelyields barrel dimensions, andcasting + minimal sizing to groove dimensionssports least leading and best accuracy...
That's what the books might say, but experience is otherwise.
