Diesel Dog I have the same problem with the hornady sst which are the same as the shockwave reason the bullet diameter is 452
My t/c hawkens flinter in 50 cal. shoot excellent with the REALS conicals in 320 grain a wonder wad and 80 grains of 3f goex,another bullet that will load easy and drop deer in there tracks are the t/c 240 grain cheap shot sabots .
