New Englanders have a 1:48 twist designed for sabot or round ball.
Doesnt. Twist and bullet weight will decide much of the accuracy. Long barrel for magnums because of the amount of powder being burned is important. Otherwise short barrel in any rifle will just increase muzzle flash and report.
The ramrod puller is used to remove bullets from a muzzle loader rifle without firing it or in the case of a mis-fire with a stuck bullet. The puller has a worm screw on the end of the ramrod or a pair of spiral wires. Drop the ramrod with the Puller on the tip into the barrel. Grip the ramrod and twist it such that the screw will dig into the bullet. Then pull on the ram rod to loosen the bullet and extract it.
Insure rifle is unloaded. You will need a cleaning rod, bit of masking tape, marker, ruler, and an oiled patch. Use tape to make a "flag" that wraps around the rod near the handle. Place oiled patch (large enough for snug fit) in the barrel, push down until tape is near muzzle. Note where tape is pointing. Mark rod with marker at muzzle. Withdraw rod, allowing it to rotate, until tape "flag' has rotated back to original direction, having made one full revolution. Mark rod again at muzzle. Measure between the two marks. If it took 12 inches of rod to turn one full revolution, that is a 1 in 12 twist- or one in 10, 1 in 6, etc. VERY slow twists for a muzzle loader may mean you use 180 degrees of rotation, and double the measurement (1 in 40, etc)
Take a cleaning rod with a non-rotating brush, push it into the muzzle about four inches and stop, mark a line on the cleaning rod with a magic marker right at the muzzle, put a tape flag at the end of the cleaning rod or at least 16" from muzzle, push down on the rod and watch the rotation of the flag, when it has made one revolution, stop pushing, put a mark on the rod at the muzzle, pull the rod out , measure from one mark to the other and you will have the rate of twist for your rifle.
1-7 barrel tw = -6
The Browning 2007 Product Catalog states that the A-Boltchambered for 25WSSM with a 22" barrel has a 1 in 10" rate of twist.
I own a London Fine twist double barrel shotgun in fair condition, it was rated at $100.
twist is 1:9
Rifling imparts spin that stabilizes the projectile. The rate or "twist" determines how much

It should be stamped on the barrel
In relation to firearms, it has to do with the rate of rifling in the barrel. Rifling is the spiral grooves that puts a spin on a bullet to increase it's accuracy. "Barrel twist" is the rate of spiraling or inches per turn. That is the length of barrel it takes to spin the bullet a full 360 degrees.
