Just goes to show any company can make a bad bullet.
I get failures to fire occasionally with 22lr ammunition. Some brands more than others as we all do.
Today I got a surprise. I had an Eley Tennex(their best match grade ammo) fail to fire in my new CZ 457 match rifle. I hit it twice in the same spot to be sure. No bang. Big surprise for what is supposed to be the best ammunition out there.
I removed it from the chamber and turned it so it would strike a different spot on the rim and it did fire that time. It even went in the group with the rest.
Just bad luck I suppose.
