Blown Smoke

A lot of people might indicate that a 1/48 will not shoot sabots effectivly. Couple of problems exist - the twist itself and the deapth of the grooves..

I have found that my 1/48's will shoot 300 grain bullets with sabots really well - I mean realy well, but when I back down to 250 grain things really go in the trash. One gun the Lyman will not shoot 44 cal 300'swell either but the other TC's do not care whether they are 44 or 45. The 50 cal TC's shoot the .458 300 - 350 grain bullets very well.

So my inclinenation is to tell you heavier longer bullets I hope that is what Lee's formula says. But each gun is a bore un-to-its-own...
