I've had this question in the back of my head at certain times in my shooting career.
Does twist rate effect muzzle velocity?
In my mushy Grey Matter, I would think, that the faster/tighter the twist, the slower the bullet would exit the barrel, all things being the same of course (barrel, ammo, temp., alt., blah, blah, blah). Reason being, more "friction", due to a smidge more rifling/lands in, say, an 18" barrel.
My theory, anyways, a 1-n-9 twist would exit the barrel at a higher muzzle velocity, than a 1-n-7 twist. Due to less "friction" and less lands (rifling) in the barrel.
I realize, we are talking hundredths of inches, possibly less, possibly more. I do understand, the faster the twist, the more accurate a certain weight/length bullet is, and the fact that lighter/shorter/thin jacketed bullets will vaporize in a too fast of a twist barrel.
Just curious if this is a correct assumption, or I'm dumber than I originally thought.
Please don't hate me, I didn't Google Foo this, just popped into my head while I was watching the snow flurries blow around outside.
Thanks in advance for squaring me up and setting me straight.
Ok, let the twist rate games begin!
