With my Henry Levergun in .357, I send any .357 grain through her reliably. When I go to .38 sp, my manual states using .38 sp in no less than 158 grain. As far as What brand, everyone here is gonna give you personal "Opinions". Some may load & shoot better than others. Here's plenty to choose from below. Grab a box, see how they run, then buy more.

The best 357 Magnum ammo for a lever-action rifle depends on your intended use Raymond, but Hornady LEVERevolution 140 Grain FTX, Federal HammerDown, and Winchester Big Bore 158 Grain SJHP are highly recommended for hunting due to their optimized design for lever-action feeding and performance. For target practice
158-Grain Jacketd Hollow Points (JHPs) or Soft Points are good general-purpose options for paper and steel targets offering a balance of availability, price, and performance.
Hope the above information helps Raymond Sir, happy shopping Bud!!

The best ammunition for a .357 Magnum lever-action rifle is Hornady LeveRevolution 140 Grain FTX, which is specifically designed for lever-action rifles and offers exceptional accuracy and performance due to its polymer-tipped bullet that safely rests against the primer in a tubular magazine. This ammo provides a flat trajectory and high velocity, making it ideal for hunting and target shooting.
