Have any of you ever used the Hornady XTP JHP in the 180 gr bullet #35771 in the .357 Mag rifles, either Rossi or Marlin? If so, what powder did you use and how much and what accuracy did you find?

Let's keep this simple. W296/H110 or #2400. H110 and W296 ae just different lots of the same powder. I don't shoot jacketed bullets in my .357 mag. handguns and I don't have a .357 mag. rifle but those are some of the best powders for that purpose. I did use those powders in a Marlin .44 mag. rifle with very good results.

the new rossi [taurus,torous,touros,torous,tarous, however you spell it] rifles have a bbl twist rate better suited to the lighter [125gr] bullets.
basically making the 357 a 32 magnum
if you do try the heavy weights you will have to push them to top velocity's to have any hope of stabilization.
i know their older [rossi] ones will stabilize the 180's though, as mine will.
marlin done the same thing to their 44 bbl's copying the slow twist rate for the 44-40 with it's 200 gr bullet.
I use 158 gr XTP , no 180's, and 13.8 gr og 2400 in a Handi Rifle. I get about 1.25 groups on my 75 yard range.
