Keyhole Problems

[Drew_CarreyAB]

Well the scope was bought about 6 years ago from a pawn shop...It was a 4x12x40 with an adjustable objective and had an electro point illumination system....... the sight itself is what I want (the scope tube is bent and kinked, so its garbage). The sight had a 3-4mil dot in the center surrounded by a ring and then there were 2 verticle and 1 horizontal(bottom) lines in the sight picture but not touching the circle itself. I thought I had a picture but I can't find it right now.

Rocky, I have the CastHandbook from Lyman. So wat you guys figure is to use up some of the wheelweight bullets that I cast(I have like 1-200 of them) and then drop some gas checks on? If I use the gas checks where would I find info on load data?? The Lyman book only gives a max velocity of 1550 fps using Green Dot. Is there other powders I could use i.e IMR 4350, Re 19, etc.etc???
