Hi guys just going to throw out a general question here. How old is the .300 Black Out Cartridge?? I was at Cal Ranch today looking at AR-15's one of them there was chambered in 300 Black Out. The gun counter sales guy I have known him a few years told me yea they claim the .300 Black Out was used in the Vietnam War but when he said that he rolled his eyes so I knew he was kidding. I replied I thought it was out just a few years. My thoughts were 5-10 years. But thats my question!

300 blackout has only been around a few years. 300 Whisper has been around since the early 1990s.

Wikipedia says
" Pioneering work by the USAF Armament Lab at Eglin Air Force Base in the late 1960s produced the 7.62×28mm cartridge which propelled a 172 gr match projectile to the 1,050 ft/s (320 m/s) range but suffered from various reliability issues. "

300 blackout is 7.62×35mm and not 7.62×28mm so maybe that's where the confusion came from.

I am just curious, I would much prefer a Ruger Mini30 I think the 7.62x39 is a more versatile caliber. I know I will catch flack on this one. No matter lol

It would be if there were as many .311 bullets as .308 and it had a fast enough twist to stabilize big bullets.

If you reload your own ammo the 300 blackout is more versatile. That caliber leaves you with an abundant supply of 223 brass that can easily be converted into 300 blackout and you also have a wide selection of 30 cal bullets ranging from 110 grains all the way up to 250 grains. With 7.62x39 the brass is much harder to find and the bullet selection is limited. If you don't reload your own ammo then 7.62x39 makes more sense. I reload both 300 blackout and 7.62x39 including 30-30 win and 357 magnum. Each one of those calibers has their advantages and disadvantages compared to the others and in a lot of ways they are very similar. If I was going to pick one based on versatility I would pick a 357 magnum rifle because it has almost the capabilities as the other calibers, it's easier to reload and you can also use 38 special in one as a 22LR substitute. Not to mention being able to also have a handgun in the same caliber. It's hard to beat that versatility.
