Good to see those bullets working for you Eric and the ongoing reports are good value also. I've just been casting up some 700 grn gg bullets for my 50 x 2 1/2" and looking to give them a run in about 2-3 weeks time at a competition. I've trialled about twenty of them over 500 yds on steel and they seem to be holding vertical very well. Well, that is as good as I can hold anyway. Generally keeping to 1.5 and under 2 moa. It certainly lets you know its going off though ! The big fifty is a very reliable distance performer if one can maintain their trigger control and composure.
