I can't find an estimated pressure for the load I am interested in in any reloading manual,, have searched here and find tons of info but not exactly what I'm after,,,,
.45 cal pacnor, 195 barnes+sabot, and 54 and grains of H4198 as a min,,,,58 grains as a max,,,,,
If someone knows these numbers can you please post them?

:)pp I don't have the numbers in front of me but it's low to mid 30,000. Edge could be more exact with some velocity numbers.

QL would estimate .45 cal pacnor, 195 barnes+sabot, and 54 and grains of H4198
approximately 2500fps and 37Kpsi
58 grains @ 2600fps and 39Kpsi.

Thank you very much,, all I could find was with a much heavier bullet and powder load for the .458 winchester

Most folks do not reach the predicted velocity shooting sabots.
If you reach the velocity then the pressures are probably close, but if the velocities are higher or lower the the pressures are most likely higher or lower too!
