I don't have a chronograph. This is a dissadvantage, but not too critical since I don't load to the max.

I was wondering if someone could give me the projected velocity and pressure of the following loads:

.458WM
530gr cast bullet - 1.305" long
loaded OAL: 3.15"
case length: 2.487"
bullet in case: .63"

50gr IMR-4895
55gr IMR-4895
60gr IMR-4895

Thanks for any help!

You didn't say what length of barrel, so I put in 22"
50gn 1550fps 24.5ksi
55gn 1707fps 32ksi
60gn 1862fps 41.6ksi

Thanks so much. This is a big help!

BTW - Its a 24" barrel (Ruger #1) so I'll just assume a tad more velocity.

Bob.
