These 158 grain came out of my 20 inch Rossi at 1500f/s when it is 60F outside. I need to use loading die to crimp the neck for better feeding for rossi r92. Shooting out of revolver is no problem. Best value 357 Mag on market will buy more

About New Republic Training and Range 357 Magnum
This 158 grain 357 magnum FMJ ammo is built around a Full Metal Jacket Flat Point projectile, brass casing, and Boxer primer. Full Metal Jacket bullets are generally used for range work because the jacket helps support smooth feeding and consistent practice, while the flat point profile is a common choice in revolver and lever-platform ammunition categories.
New Republic ammunition in this Training and Range load is engineered for 357 Magnum firearms and intended for practice rather than hunting or defensive expansion. Its listed 1296 fps velocity and 587 ft lbs of muzzle energy help distinguish it from lighter-feeling practice loads, while the manufacturer notes stable, predictable recoil for repeatable drills.
