500 Wyoming Express - 500 grs

[Lee Martin]

Quick follow-up on the Wyoming Express

1) The brass easily takes 500 gr WFNs (same nose as the 440 so OAL isn't a concern)
2) The factory blade height works fine for the 440 & 500 gr weights.
3) 25.5 of H110 just clocked 1,287 fps with the 500. The 440's did 1,356 fps ahead of 29.0

Leadheads 500 gr WFN & a loaded 500 WE:

Those are some pretty good numbers, Lee. Are the WE and JRH 500's running at the same 35k psi as the 500 Linebaugh, or do they bump up the pressure a little more?

From what data I've seen it costs 7-9000 psi increase in pressure over the 500 Linebaugh.

Definitely running them higher. I would guess to the tun of the mid-40,000 psi level or thereabouts.

Thanks, Whit. That makes sense.
