Sorry, I just can't stomach anyone calling a Ruger product "svelte", especially compared to a S&W. Rugers are sturdy and functional, but relatively unattractive and unrefined.
In your opinion. I'm particularly fond of my Rugers and this one pees on .44 mags, let alone specials.
And quiet frankly, I'd have to see with my own eyes a .357 loads that exceeds 1,300 FPS with a 180 from a snub before I buy it. I've played with the round quite a lot, and in my experience, that kind of performance can only come with loads (significantly) in excess of max.
Always nice to be called a liar.
My chronograph is my proof, but hey, buffalo bore seems to have achieved a similar result. My load is 13.8 grains AA#9 and a 180 XTP if you are interested. It's full power/pressure. I developed it for hunting in my 6.5" .357 Blackhawk. It clocks just over 1400 fps/785 ft lbs in that gun. I just decided to quit listening to the armchair experts one day when I got the little SP101 and went and chronographed a bunch of loads in a bunch of barrel lengths.
I must say, BB got way more out of the 125 grain load in the snubby than i did. I have a feeling that I could get more with a faster powder. My load is 18 grains 2400 with a 125 Sierra JHP. It was somewhere in the mid 1100 fps range IIRC, rather unimpressive since my +P 9 from a 3" barrel slightly betters it with much less flash/bang. Not sure how BB got a 125 grain load to perform in all barrel lengths as they did. But, hey, they have the resources and the desire. I got 550 ft lbs, 1330 or something out of a 140 Speer JHP so that's what I carry. Heavier the bullet, the slower it accelerates down the bore and the more of the pressure peak it catches. That's my theory, anyway.
