jonm Beat the snot out of. Get real. It has maybe so little if anything extra in the hands of a skilled loader when both are loaded to there max it does not matter. The cylinder on my 44 is 1.762 That lets 325gr LGC bullets torun over 1300fps at only 1.710 length. Or to go to up some 350gr bullets.
Yep the ruger/contender only 45colt can throw 400gr bullets but to match velocity at 300 or 355 gr your testing the limits of many. Those load should include the dan wesson revolvers ha. Guess what I have. I do have to say my normal load for the 44 is a nosler sp 240gr at 1490fps. Bigger ain't enjoyable.
This still does not take away from what a 357 can do with good shooter skills .
