Barry, Eric and the gang over at Moss Pawn in Jonesboro, GA have converted over a Hi-Point pistol (presumably a .45ACP judging from the magazine) as well as a carbine by the same manufacturer to shoot the 10mm Auto round.

They shoot 100-rounds of Cor-Bon 135-grain Powerball, which is a pretty hot load in the 10mm Automag (.41-Magnum.) They got 10-inches of penetration out of the round in ballistics gel with an expansion about the size of a quarter. It could very well be the only strait blowback 10mm pistol anywhere in the world. For about $169 plus the conversion, it's hard to beat.

Then a few weeks later, they moved to a 10mm conversion of a 4095TTS carbine. The only issue seemed to be in that the recoil spring was too week, forcing the small rifle to cycle too quickly on occasion, overriding the bolt. The carbine used for the conversion and tests seems brand-new out of the box as it still has its yellow and red stickers on the buttstock. The last part of the video shows them firing from a bench at a 100-yard gong and hitting it loud and clear. It's one of the few 10mm carbines, and probably the most affordable at $315 plus the conversion.

Why the 10mm Auto?

Back in the late 1970s, a group of firearms engineers working on what would later be the controversial Bren 10 pistol visited firearms guru Colonel Jeff Cooper to get his input on the ultimate handgun round. After several months of talks and some final tweaking by Norma cartridges of Sweden, the Centimeter round was fully developed. As you know, a centimeter is 10mm and by 1983 the 10mm Auto burst onto the scene. Using the case of the old .30-caliber Remington carbine round with a 25mm length, the 10mm Auto remains one of the hottest and most powerful production handgun rounds in history. Typical loads range from 135-200 grain bullets but all deliver over 600 ft. /pounds of energy and approach speeds of almost 1600fps.

The 10mm outperforms the .40 S&W by 200250 ft. /s on average for similar bullet weights and has a pressure of more than 37,500 psi, some 2,500psi higher than the .40S&W. However it still delivers about 100-ft pounds more energy than the average .357SIG round, for about 2,500psi less pressure.

In short, a superhot, hard-hitting round is hard to beat. If they can make a Hi-Point 10mm, that is revolutionary.
