The problem is that there are quite a few folks out there that just cannot seem to understand that a rifle bullet that is no longer moving at 2,000 fps, give or take, is not really much of a rifle bullet any more. He is a Glock and Smith & Wesson Certified Armorer as well. There's a narrow band of powders that work well with the .300 Blackout.

"Not cycle" can mean several things - does it extract and eject the fired round but not feed the next round, something else? Typically, these bullets are the product of thousands of hours of computer-aided design and testing and are much more expensive to make than standard practice ammo, but theyre well worth the cost. Solution for 300 AAC Blackout jamming! To get down to the nitty gritty; live rounds are "being left" in the chamber. In addition, my testing revealed it is relatively easy to assemble .300 AAC Blackout handloadsboth subsonic and supersonicthat are more accurate than factory loads. The Glock 17L has a 6-inch barrel25% longer than the Glock 17but only produces muzzle velocities of about 1,280 fps, or 10% greater than its shorter-barreled little brother.
