Was out shooting my 221 Fireball (CZ 527 rifle) a few days ago, testing some handloads with 50 gr bullet & H4198 powder. Id used this combo before, usually use F205 gold medal match primers. I was given a hundred Federal '200' primers which were stated on the box as being 'Small rifle primers & high velocity pistol' so I figured I would get rid of some
here is what my first shot did, I pulled the rest of my ammo. It chrony'd @ 3035 fps which is not unusual (or high pressure) for 18.5 grs H4198 & 50 gr bullet in my gun.
