I am very happy with HSM .44-40 200 grain Cowboy loads. Velocity is moderate, and accuracy good. They are sized/tapered such that they run -well- in a very ammo picky replica 73 carbine. (An early Uberti with the serial numbered parts). As a general rule on “cowboy” factory loads, or commercial reloads, always check the actual bullet weight and published velocity. Many are -way- heavier and hotter than needed for our sport.
