Semi; Its because I don't have any .45 cal balls! I did pick up a box of TCs .45 maxis, 270gr I think, they had some 320 maxihunters too. Also they had a scope base (old style 9930) if I remember right. They also had at least 3 bases for round bbl tcs. New englander, PA hunter, that take the weaver style rings!! So anyone is interested I can get the info or the bases and send them. cost+ shipping. They were around $15.00 or so, less than $20
