I guess I don’t understand the concept of barrel twist vs. velocity in long guns.
Is a a 1:20 twist more accurate vs. 1:10? Wouldn’t that need much more powder?
I only bought the AR and SCAR because 0bama was going to take that right away from me.
Give me a shotgun and I can knock the eye out of a burglar at 10 feet...if my contacts are in.
But I used to have my way with dove and ducks though.
The longer the bullet, the faster the spin rate needed to stabilize it. That means heavier bullets need a higher spin rate, 1:9 is faster than 1:12 (one turn in 9 inches vs. one turn in 12 inches). But a light bullet spun faster than needed is less accurate than spinning at the least rate for stability. That is why varmit rifles often have a slower spin rate...because they are made for light, explosive bullets.
Heavy bullets need a faster twist in order to stabilize. Otherwise they will tumble. A longer barrel will typically give you higher velocity - more time for powder to burn. You can use a slower burning powder. I’m not sure, but guess that would give you a lighter recoil too.
