These are the velocities I got with 240 grain bullets in my Marlin 1894. At 100 yards a 44 Magnum from a rifle hits my gong targets very hard.

I was never interested in the 357 Magnum out of a rifle. Sure it will have less recoil, but I want more power.

I always thought using Kinetic Energy (mass times velocity squared) as a comparision between bullets was bogus, since only momentum (mass times velocity) is conserved. Gunwriters love KE because it squares the velocity and it is a lot easier to increase velocity, and thus KE, than increasing momentum.

The 44 Magnum has more momentum than the 357 and always will.
