and realistically a hot 44 can put out as much energy as a 454 (BB's hottest load).
A 44 Mag is not within the same county as a 454 in any performance load. Marketers lie, chronographs don't. The minimum length for useful performance in a 44 is 4" and 6" in a 454, IMHO.
That was a great post by JMORTIMER. I'm a believer in the 45LC, also.
