Hi Donna
Nice looking bullet. It looks alot like mine, which happends to be .429 dia. and fired in my 444 Marling lever action. Mine is a 300 grain, and I make it out of 1/2 inch copper tubbing with the dies from Richard. I make mine round nose and flat point, but I only get 1 inch group at 50 yards for 3 shots. I`m happy with that though, because, where I hunt, it is really brushy, and 50 yards, is the maximum for deer.
By the way Donna, what rifle were you shooting that in?
thanks
bullet maker
