Starting this thread for my brother. He's having trouble with consistent groups. Turned him on to Thor bullets I use. He's in ID so the gun has to have #11 caps and no sabots. It's a T/C Hawkins with green mt 1-28" twist. What gr./type of thors do you guys use. What type and gr. of powder. He's calling in tomorrow to get the sample pack to gauge bore diameter. BTW mine is CO legal so my setup wont help.
