Video Transcript:

The Brazilian ammo company Magtech has a history dating back 80 years. Their plant in Sao Paulo doesn't just load the ammo, but also produces the powder, primers, cases, and projectiles allowing for superior quality control. Magtech's parent company, CBC, is the largest provider of military ammunition in all of Latin America. They also own the popular European company S&B. Magtech is known around the world for making quality, reliable ammo in a number of different calibers for all kinds of shooting activities.

The round we're looking at today is one of several of Magtech's revolver loads. This one is a .357 Magnum, and like most of their ammo, features a re-loadable brass case with a non-corrosive primer. The bullet is a 158 grain semi-jacketed soft point. This is a versatile bullet type that is suitable for self defense or hunting, but it's still economical enough to use for practice on the range.

The flat point lead tip is good for both penetration and expansion, and the partial jacket prevents excessive lead falling in your gun's barrel. There are more technologically complex expanding rounds available, but the semi-jacketed soft point .357 bullet has been used successfully for decades by everyone from hunters to law-enforcement.

The trade-off, however, is the relatively stiff recoil. We tried the ammo in six different guns, including five revolvers and one carbine. We found recoil impulse to be on the harsher side of the spectrum for this caliber-- especially in smaller revolvers. It was tolerable in small quantities with our Smith & Wesson K-Frame Model 65, but I can only manage a couple of shots in the lightweight Ruger LCR. The Marlin carbine and the Taurus Tracker with a six inch ported barrel handled the round fine, and except for emergency self-defense situations, this load is probably better suited for heavier guns like these.

Recoil aside, the ammo functioned well in all of our guns except for the Smith & Wesson 686, which experienced a couple of light primer strikes. This particular revolver has a modified trigger that doesn't always work well with harder primers, but if you stick with factory weight trigger springs, you shouldn't have any problem with Magtech ammo. We took the Marlin 1894 back to 20 yards to test accuracy from a bench rest. The ten shot group we pulled off was pretty impressive, with a spread of just under an inch and a half.

Magtech is not as well known as some of the other domestic brands that you might be used to, but in each of our ammo tests, it's proven to be a reliable and consistent performer. This .357 semi-jacketed soft point is a great choice if you need an affordable Magnum load with an expanding bullet.

Customer Reviews

excellent rounds. Review by James
Bought two boxes of this Magtech for a S&W pro revolver that I just purchased second hand. Wanted to make sure I shot good loads in a revolver I hadn't shot before. I was not disappointed. The ammo performed very well. Very clean. Good tight pattern at ten yards. Powerful loads and accurate. One problem, I got carried away and shot up all that I bought. Didn't save any for concealed carry. I am going to order more. Delivery from Lucky gunner was fast . Fed Ex was at my door on the third day. (Posted on 12/13/12)
