30Short&Weak was tongue and cheek and was to imply that those "intermediate" 7.62x39mm rounds are for sissies, hence the reason I differentiate from 7.62Nato...... To think, I was simply commenting on what people typically assume if I mention I'm taking a 7.62 out shooting, they jump right to 7.62x39mm rather than 7.62x51mm.
Gosh, I go out of my way to try and be funny and it flys right over someone's head. See, it was something akin to how the 40S&W is lovingly called the "Short&Weak" by those who like the 10MM Auto. I'm more a fan of the 7.62Nato and that's why I find it funny to refer to the 7.62x39mm as a "short&weak" in comparision to the 7.62x51mm and have used it in response to the assumptions by others that I meant 7.62x39mm.
I own an SKS and yep, it almost goes through that 1/4 inch mild steel plate while something like a 7.62Nato or 30-06 Springfield goes right on through...
Then there's my 300WinMag which is almost making it through 1 1/4 inches of steel plate, guess it makes the 7.62 Nato "modest and conservative" if I refer to the the 7.62x39mm as "short&weak".
Anyhow, I am a handloader and recognize the obvious differences between the rounds. Sorry I got you all rialed up.
