All .45/70 rifles I have read about tend to have a slower twist rate barrel, commonly of 1:20". Am I correct to assume that a .45/70 barrel 1:20" twist rate could have a hard time stabilizing a subsonic 500 grain or heavier bullet? Would I want the projectile to be spinning at a higher rpm?
Since I am interested in stabilizing a heavier bullet at subsonic velocity, is anyone aware of any particular make and model of .45/70 rifle with a faster twist rate such as 1:14" on a factory provided barrel?
