Can you run the numbers on a .58 shooting PRBs? Right now I am using 100 gr of FFg and getting phenomenal accuracy.
100 grains of 2f in a .58 caliber according to T/C Owners Manual
1428 fps 1263 foot pounds of muzzle energy. Max load recommended is 120 grains of powder.
80 gr if 2f = 1302 fps and 1050 foot pounds of energy. More interesting is they claim 90 grains will be most accurate in rifles. Mine likes 100-110 grains in my GMB. But it does shoot very well with 90 grains. I just felt, like Semisane if I could push it that little bit harder, it would be more ... "deadly."
