Yes very true. It is much cheaper to fire .45acp in a Kirst conversion cylinder. Any normal saami spec. .45acp load works great. And fall out just nicely when poked lightly with a pencil's eraser side. Wadcutters both lead and fmj in 180-200 grain weights are very accurate in them. Nice to see those perfectly cut holes form cloverleaves !! I have fired upwards of perhaps 1000 or so .45acp's in mine without a hiccup.And that includes of course the usual fmg 230 grain standard load variety. Cheap as hell if you buy .45acp in bulk. The Kirst .45acp cylinder shows no signs of wear at all. Indexes perfectly and the lone firing pin always detents the primer very well. A testament to their high quality. I too have the R&B Howell cylinders for the .45 Colt. Also quite good in its own right. But for sheer fun on the cheap, the .45acp conversion is hard to beat !! .....So much fun, so little time !!
