I shoot 190 cast bullets in my .303's. In fact, that's the bullet that led to the demise of the one I posted above.
Nice. I love that big flat meplat. Shades of Elmer Keith. I never got into casting and am kinda old to start now. Of course, I guess I could find someone who casts and sells some once in a while and just order from them. That looks just like the jacketed ones for sale. Two feet long.
I might add that you may be the only person in captivity who produces a flat meplat 190 grain gas check in .308 caliber. Pretty rare company.
