To recap.
The data mule deer posted from Hogdon
44 Magnum, 8.275” barrel:
240J 1582 36,200
270J 1439 38,300
300J 1325 38,300
325C 1368 38,100
330C 1350 38,800
355C 1247 37,900
Average pressure 37,933
.45 Colt, 7.5” barrel:
240J 1532 30,000
260J 1374 30,000
300J 1203 29,800
325C 1266 27,400
335C 1240 28,000
360C 1167 29,800
Average pressure 29,167
Compares the 2 cartridges at different pressure levels
Max load from Hogdon reloading web site shows a max load for a 325 grain 44 bullet of
Grains22.0 H-110
Velocity (ft/s)1,368
Pressure38,100 CUP
The 45 colt Ruger only loads or not loaded to this pressure level but the 454 is
Grains26.0 H-110
Velocity (ft/s)1,511
Pressure34,300 CUP
That is 200 FPS more velocity with 3,800 Les CUP pressure it is not meaningless.
The 454 loads were loaded to over all length of 1.760" this overall length and case capacity can be equal led in 45 colt brass
The data posted by mule deer shows the pressure level an average of 8,766 psi lower in the 45. The dat that I posted also from Hogdon shows a pressure of 3,800 psi lower again in th 45, but at this level the 45 with same weight bullet is 143 FPS faster, showing the internal ballistic superiority of the larger diameter 45 over the 44. This is a fact that refuses to be acknowledge by a poster. He discounts it as meaningless, while claiming that .429 is larger than .452, the logic escapes me and goes against every experienced handgun hunters experience on large game.
