Webley Bulldog Repo?

[vba]

Average pressure for the .455 Webley round is 13200psi.
For the .45ACP it is 21000.
How to measure.

I have loading manuals that have pressures listed and some that don't. On the latter simply use the low range of the listed loads or use the listed velocity. We know that the velocity of the .455 with a roughly 255 grain bullet is in the 650 fps range.

Check out Lew Wallace's pictures to see the little sharp stud I was warning folks about behind the trigger.

Nice stuff LW thanks for posting.

The old 1981 edition of NRA's "Handloading list a 185 grain jacketed SWC on top of 5.1 grains of Winchester 231 as producing 11500 CUP and pushing the old training bullet at 765 FPS. Plenty fast enough for punching paper.

Please do not use this data without checking it yourself. For one thing powder formula have changed and storage techniques alter powder performance.

Unfortunately not all their loads have chamber pressures.
