NOE's website shows the 37gr GC molds are out of stock except for the 5 cavity and they are over $100 without shipping. I've been trying to shoot 45gr cast boolits out of my RIA 22TCM, but the 1:16 twist won't stabilize them very well. I'm 99% sure the 37gr would stabilize and shoot well, but at I'd rather not spend that much without knowing for sure.
thanks in advance,
Chris
