RE: TC System 1 Twist rate?
Ccmano : 1 in 38 twist is the same twist I have in t/c thunderhawk 54 cal. ,I can tell it will handle sabot bullets with excellent performance.
I have shot the precision qt's 45 cal. in 350 grain sabots ,now I am shooting the noslers full partition 300 grain 451 dia: with 95 grains of pyrodex select powder.I have tried the triple 777 powders in my thunderhawk and seem to favor no more then 80 grains to shoot excellent groups.
