Are these still within .45 Colt Bisley Blackhawk limits?

I had loaded a bunch of 315 gr. hard cast over 10 gr. of Unique mainly for my Alaskan
but would like to use them once in a while in my Bisley.

I was getting 940 FPS average out of the 2.5 barrel Alaskan.

Just starting on some 250 gr. hard cast with 9.5 Unique for plinking with the Bisley.

The Bisley will handle any of the "Ruger Only" 45 Colt loads

Like he said,"Yes."

It will handle the Buffalo Bore Ammo heavy load:

Heavy 45 Colt +P Pistol and Handgun Ammo
Heavy 45 Colt +P Ammo - 325 gr. L.B.T.-L.F.N. (1,325 fps/M.E. 1,267 ft. lbs.)

Here are some ideas:

Hodgdon's 2008 Annual Manual

Cast Performance Bullet Company 325 gr LFN

21 grs H110 1109 fps 18,100 CUP

24 grs H110 1266 fps 27,400 CUP

COL = 1.680" DIA = .452"
