Here is one recovered from a goat shot at 40 metres velocity 1021FPS,
I size them .310" so they will work in .308 win and 7.62x39 the 39 bore diameter is .300" groove diameter is .310" the .308 win is .300 x .308"
cast bullets generally require .001" over groove diameter to seal properly, if you use Trail Boss powder it has the same burn rate and pressure curve
as Black Powder and gives the bullet a hefty boot in the base to obturate it into the rifling, Don't try loading much above 1100FPS in the 7.62x39
it will more than likely strip lead from the bullet and foul the barrel, So far no one has complained to me about getting any lead fouling with these bullets.
