Green Mountain called and said the sharpshooter barrels are ready. Mine is on the way. They will not sell it without the scope though,which is to bad. It is a 1:24 twist. The heaviest 50 cal conicals I have are around 385 gr. I only have 3 kinds to experiment with. I need to find some different conicals . If anyone knows of a good heavy conical let me know. I have Maxi ball, maxi hunter and great plains bullets is all. I was thinking of trying something in the 450gr range. What do you guys think?
