Hey Don

[Kurt]

Thar 1/19 twist just will not stabilize a bullet with a long radius nose like the Elliptical or money bullet type of nose past 600 yards even as hard as the .44-90 drives them at close to 1400 fps they really loose it past 600 yards.
I have the KAL elliptical the prolate and the money bullet GG and PP they just dont stay stable past 600 especially when the wind picks up.
I made up my mind to stay with a postell or the original profile PP for the 1/19 twist at 1.3" long it will reach the 1K in good shape.
My heavy .44 100 with a 1/17 twist the KAL and the prolate are doing good but I have not shot it past 200 yards but blowing out cases shooting 67 rounds 9 rounds put holes around a large 3" hole with no paper in it's center and I have to drive the brass into the chamber and use a rod to get fired cases extracted
