You are talking about the Pro-Hunters and 777 primers... this is no big deal. The 777 primers are a little biger than normal and due to the tight tolerences that TC has the hammer is not cocking. Although I shoot these primers in my TC without a problem, the easy fix is just to switch 209's.
I'll try a t7 primer tomorrow on a pro- hunter , i just tryed one in my encore no problems what so ever.
i will also try the remington ML primer just to see if that makes any difference.
and yeah i mic ed a t7 primer it is .oo6 longer than a remington ML primer.
