I'm shooting 110 gr. of fff Triple seven with the expanders and shockwaves. With the 410 gr. GP, I was shooting 95 gr. of the same. The primers are the Winchester 777 primers. Here are some of the groups I shot back before the season with the250 gr. expanders and some 385 gr. GP concals.





I'm wanting to play a little bit more with the charge size and probably try some different primers to see if I can shrink those a touch further. I can definately live with those groups, but it never hurts to tinker a bit in the off season.
As far as the teflon tape goes, I haven't tried that yet. I've been meaning too but just haven't gotten around to it, so I can't comment on that.
