Thread: 22 Hornet - Over Length Fired Once Cases?

The bullet I am using is the Sierra #1385. It is a hollow point, flat base, and has a reputation for being relatively hard (which I wanted in caae I came across a goat). I have found it to be accurate, effective on game and readily available in shops (at least until the last couple of years). The 20 shot test on one case was neck sizing only. I did the same test on another rifle, a Martini small action (which is effectively a rear locking action in contrast to the front locking action of the BRNO465). Again, I went through 20 shots on one case with more life left in the case. I had the same problem of the neck hardening over the 20 shots but without any sign of neck splitting. The neck hardening did have an effect on velocity consistency. I did try larger charge weights of Lil Gun which produced higher velocities. But the cases showed distinct signs of overloading and lasted only about 5 shots. I used Remington cases because the capacity of this brand was the largest of those I tested (Win, Rem, Fed, Norma, S&B). The chamber in both rifles was cut with a minimum spec reamer.
