I am shooting a TC Omega 50 Cal with a 3x9x40 Leupold scope,using 150 G Pyrodex R/S loose powder and a 250 G Hornady SST bullet.
3.5 Hi at 100 Yds and 7.5 low at 200 Yds, Range tested not just gessing !!!. This gun will hold a2 inch group if I do my part. Try playing with the loose powder and a heavier load and see what You come up with. The TC were made to shoot 150Gr loads. just look at the new scopes from Nikon with the built in bullet drop comp circles, all set up for the 150G loads.
Just my 2 sents, there I go again thinking of hunting,
Tinks and Golden Estrous maybee 3 sents Trails End.
Deer hunting is an obsession.
