Thread: 308 barrel length velocity loss

Realistically I keep most of my general hunting sub 300y but I'd like it to be able to still give a red a solid tickle at 475y which isn't a hard shot with this old vanguard of mine.

So the question is what sort of velocity loss would one expect going from 20" to 16"?

Gunna ask....what do you mean by handier?

I see guys chopping for ease of shorted and less tangles in the scrub etc....but really.....guys chop a std no suppressor barrel and suppressor and think it's shorter and better for the scrub....all you do is chop 4 inches and add it back on.....

So why change what's working
