rifling

Early rifling cutter boxes were made of hardwood or brass.

22 rifles were not necessarily made with the most expensive or best quality steels nor was the rifling especially deep.

If you look across the muzzle in a good light, you can see the ends of the rifling lands (the raised portion).

Remember, Hastings Paradox slug barrels are truly rifled -- unlike the English version which featured rifling only several inches from the muzzle.

Rifling was not needed to stabilize a projectile due to close ranges.

I prefer some sort of agreement, because then there shouldn't be any surprises like different rifling twists or substituting another make of barrel.

Rifling in service rifles then was pitched 1:78 (one rotation in 78 inches of travel).

This had shallow grooved rifling for the original .

The stories I heard of it were evidence to the nonsense: of rifling being pushed to the outside of the barrel, of a severe case where the bore was now smooth (like a shotgun) with the rifling now on the outside of the barrel, and the best one was an urban legend told me by a gent in North Carolina: he actually saw the rifling lands pushed out of the muzzle by a monometal bullet shot in a vintage double.

Its stock is scuffed and scraped and its worn rifling indicates it was fired plenty.

New loads and rifling made it competitive to 600 yards on paper.

The bore-scope showed the fine-cut rifling that pre-'64s are known for, with traces of very light pitting.

In their six grooves, Colerain barrels feature round bottom rifling that holds less fowling; square bottomed grooves reportedly retain more fowling.

A tightly patched cleaning jag rotates the ramrod almost a half turn as the patch follows the rifling the length of the barrel, indicating a rate of twist, around one turn in 66 inches.
