Hmmmmmm
Now remember : I said home made !!!! I found a whole bunch of copper at a jobsite and I melted it down with 3000 pennies, strained it and cleaned it up. Looks like it made some real fine jackets.. Man they look good. Imagine taking a balloon, blowing it up and then squeezing it in the middle. Just picture that new style of bullet. Kinda looks like a HOUR GLASS. Now I'm just experimenting but the first bactch shot pretty darn good. No key holing either.
Keep them at about 2700 / 2850 FPS they do well.They seem to be more of a 200 yrd bullet. I'll keep you posted
