I like the idea of tossing a 750 BMG round at about 1700fps would be a nice 300yd moose gun LOL. I found brass at Starline for about $1 a case. If i get one i will have MGM make it for me for my Encore, i was thinking of putting some iron sights on it too since its not a "reach out and touch someone" round. Do you know of any good sites for the 50AK?
I already have the 450BM, 375HH, and a 338WM (all my big hitter rifles)
I assume you mean a 750gr Bullet at 1700fps. If you're going to have a 12"+- Barrel, and with the powder Real-Estate that bullet length will occupy, you wont get anywhere near that velocity.
Don't get me wrong, this is a fine project. I have an applicable statement.."I can make a bowling ball, come out the end of an AR, but at that point the only thing in danger, are my toes"!
As Always, with mag loadings, start far lower and work up. These are typical loads, your results will be far different. Safety is YOUR Responsibility. If you don't know what your doing Don't-Do-This!!
