Ode to my 300 BLK rifles...
An M1 Carbine will push a 110 grain JSP bullet at about 1950 fps, giving about 950 ft lbs at the muzzle. The 300 BLK is an M1 Carbine with a hard on. A 125 grain JSP at 2200 fps (or more from an 18" barrel), giving 1410 ft lbs, or 55% more than an M1 Carbine, and even 200 ft lbs (about 18%) more than a 5.56 at the muzzle. Used as a home defense carbine, the 125 grain SST delivers all its energy to a live target in 13-15". No over penetration.
I first got a 300 Blackout AR15 in about 2013, a nice CMMG. I used it as my patrol carbine on a Homeland Security "Critical Infrastructure Protection" contract patrolling Dams and powerhouse in the high Sierra in Central California. I liked it a lot, but ammo was still hard to obtain, and even reloading, it cost more per round (at that time) than the factory Black Hills MK262 MOD1 77 grain factory ammo I had used in my 5.56 AR15. At the end of the two year contract, I sold it and went back to the cheaper to shoot .5.56 (mostly in my Mini-14)
Fast forward to earlier this year, the 300BLK bug bit me BAD! I stockpiled ammo (400 rounds of 125 grain WW OT, and 300 rounds of 125 SST Fiocchi. I still had dies and about 400 rounds of 300BLK brass.
Then I built an M4gery 300BLK AR15, and finally two months ago found the my Holy Grail of 300BLKs, a blued steel Ruger Mini-14 in 300BLK on Gunbroker. What made it special was that it was blued steel, and it was NOT a tactical model Mini. Believe it or not, I didn't want a tactical with a 16" barrel, but rather a standard with an 18" barrel. It is not a Ruger catalogue item, but was rather a special run for Davidson's a few years back. They are impossible to find now.
It came in a Hogue stock, but I put it in an early 181 Series wood carbine stock with a wood hand guard, for a blued steel and wood look. It won't frighten the "Snowflakes" as much as an AR15.
The Mini 300 BLK weighs a full half pound less, at just over 6 pounds (6.2), and the M4gery is closer to 7 pounds (6.75).
A magazine loaded with 20 of these 125 Grain Hornady SSTs is some serious whoop *****, and gives me a warm fuzzy feeling.
