I've owned a couple of Rossi M-92 clones in this caliber over the years. The older ones(>20 yrs) clearly did not like lead bullets or weights over 158 grains. A current production one I have does well with 130-158 gr hard cast bullets up to 1200 FPS, then loses it's grouping. It still doubled its group size going from 158 to 180 grain with jacketed bullets, so lighter jacketed bullets are in order.
Interestingly, my Taurus M-92 clone in 357 does just fine with a full load of H-110 and a 180 gr Hornady HP or Nosler partition, shooting 1 1/2 groups at 50 yds. Velocity averaged 1510 fps from a 16" barrel. Since Taurus now owns Rossi, it suggests that Taurus uses different barrels, at least in the stainless models.
