.500 A2 and IMR 4350

Hi everyone,

In the loading data for the .500 A2 found in the reloading pages of this site, I see charges of IMR 4350 for a 600 gr Woodleigh listed up to 136 gr in weight. I've seen a 124 gr load listed elsewhere for supposedly 2400 fps, supposedly at an estimated 50,000 psi; as I recall from the A2 loading manual something like 63,800 PSI is max operating pressure (taken from memory; don't trust this number).

I've also read that you can't stuff enough IMR 4350 into the A2 case for you to run into problems with a 600 gr Woodleigh. Can anyone shed some light on the subject of what pressure can be expected at these various load levels?

I spent last weekend shooting 647 grain milsurps with 100 grains of IMR4895 for 2230 average with little deviation. I was surprised to get that much speed with that load. I'm interested in 4320 & 4350 loads for milsurps if anyone has the data.

Thanks for the suggestion.
