Won one of these a few yrs back and with my other rifles shooting well I thought I'd load for this. But first I am in need of a trigger. The Mil spec that came with it feels like 2 inches of creep and a 12LB pull. Has anyone dropped a Timney or the like trigger in one? Also noticed they have options for small and large pins. How do I tell the difference? Probably mostly used for paper but ya never know.
