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

willie J.

I had my doubts about buying this ammo after seeing the one negative review. I am glad that I took a chance on it. After firing a box, I am very pleased with its accuracy and consistency of recoil. In my opinion it is great ammo for the price

Paul O.

Easy to shoot load clean reload rinse repeat and good grouping with nozzler match grade 6" performance 686 barrel though grain weight feels off for competition rounds they are not this only seems they are part of the training exercise

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.

It’s inexpensive but I

"It’s inexpensive but I will not purchase it again. It doesn’t work well with moon clips (S&W 327 Performance Center revolver) the relief cut at the rim is inconsistent (rounds don’t fit good in the cylinder because the rounds don’t fit the moon clips well) and it appears the primers are soft causing them to stick to the firing pin. I know some guns don’t like certain ammo so I am only reviewing it for my needs. I’m sure other weapons function great with it."
