Sorry about that. I'm looking to build an AR to take out when we go shooting and send some rounds down range. But it would be nice if we ever went varminting if it could still hold its own.Sorry, not enough info there. Too general. It all depends on your application.
What do you want to do?
VERY helpful. Thank you. I want accuracy. It will mainly be target/precision shooting. But also small game shootingthe proper rate of twist is related to the legth of the bullet- which generally is related to the WEIGHT of the bullet. Mo' is not always bettah. The right twist for what you are shooting is the goal.
ACCURACY is obtained by REPEATABILITY. When you fire a rifle, the barrel whips- left/right/up/down. A heavy stiff barrel whips less. Goal is for the muzzle to be in the identical position each shot when the bullet exits the barrel. Stiffer barrel increases the odds of being in same position.
