65BR... Unique may not be the best but I have some Lil Gun I tried for heavy magnum loads but I don't like to shoot full power 357 loads in my 4 and 2 3/4" pistols.
I get about 900 fps with the 168 gr lead Keith bullet and 1050 with the 158 grain XTP Flat Point in the 4" Security Six. Haven't chronoed the Speed Six.
IMO the 357 is not pleasant to shoot in that fairly light weight revolver with full power loads. One time I got lost in the woods deer hunting and had to signal my buddy with 4 or 5 shots out of the Sec Six to get my bearings and my ears rang for a week. I carry that gun as a sidearm and obviously didn't have ear protection on me at the time.
There is just something caustic about the full power 357. Funny but I used to own 44 mags and they never seemed to be as unpleasant to shoot.
