CZ93X62
Official forum enigma
I know--WTHeck izzat?
Continuing with the unusual/scarce mould theme, this one came to me from The Mould Guy at BRGS at least 15 years ago. At that time it had been out of print for a while, and shows no likelihood of rejoining the Lyman lineup. It was meant for the 32/20 WCF High Velocity application, and mine is a 90 grain (in 92/6/2 alloy) flat-point with a gas check shank. It resembles a Lyman #311316 that lost one of its center drive bands. It has very little lube capacity, the shank gap is about the same size and depth as its sole vestige of a lube groove. I have yet to try it in a rifle-length barrel for this reason. It "cleans up" in a .312" H&I die, and doesn't quite fully do so in a .313" die.
Where it has excelled is in the 7.62 x 25 Tokarev for the CZ-52 pistol. Using enough AA-7 powder to prompt these along at 1550-1600 FPS, they remain jackrabbit-accurate to 100 yards and beyond. Basically, start at 7.0 grains for about 1275 FPS and keep going. Once past 1400 FPS, the brass gets launched into the next township/low earth orbit, so it is nice that Starline continues to supply them. They give a satisfying THWOCK when striking jacks or ground squirrels, too.
Yes, they consume gas checks. Loading them is a mite pricey for this reason. SO WORTH IT, though.
