We call it Transitional rifling. Some will call it gain twist, progressive twist or incremental twist. We cut rifle virtually any twist into a barrel (subject to tooling etc…). We can start the twist out at 1-14 and end up at 1-7 and have it uniformly increase from the breech to muzzle.

Conventional wisdom says slower twist rates wouldn't properly-stabilize a heavy bullet. A guide on how to pair .223 / 5.56 NATO rifle barrel twist rates with bullet weights. Though far better than the 1-in-14 twist, it is still unsuited for some of the premium loads developed over the past decade.
The dowel is cut up into approximately 6" sections. The number required depends on the length of the barrel. The caliper is by far the most expensive item at about $25-$30.

Mar 27, 2008 · A 1 in 10 twist barrel, still using the 55 grain FMJ. In my opinion this was the best combination. It still caused a great wound channel, although it delayed the "tumble" for the first 3-4 inches of penetration, gave good downrange accuracy and cold weather performance.
