I bought a 16” fast-twist barrel for my 10-22, it also has a threaded muzzle. Works great.
I was surprised to see the 1 in 14 twist from the Kel-Tec pistols seems to improve stabilization of the 60 grain bullet. Very little keyholing at 15 yards.
From the Rock Island 15Y bolt gun, with a 1 in 16 twist, no keyholing at 15 yards.
