A: Thanks for reachingout Matthew! Just to be certain, this round's bullet is a soft point, not a hollow point. But its weight is more important – and at 62 grains, both a 1:9 and a 1:8 twist barrel are optimal to give the bullet the in-flight rotational stability it needs to demonstrate its best potential accuracy. Speer designed this ammo to satisfy the FBI test protocol when fired through a barrels shorter than 16". I believe a barrel that is exactly 16" long will work perfectly as well, and indeed give the bullet the energy it needs to demonstrate its fullest potential terminal expansion. All of this is to say your rifle's pretty much ideal for this self-defense ammo.
