I bought a Walking Varminter in .223 a month ago new. It took me a couple weeks to get a chance to shoot it.

The first time out 49 of 50 went off. All commerically loaded ammo.
The next day I picked up a box of Hornady Black 62g. Nine fired, six did not. I have a firing pin indentation.

Today I loaded up some ammo using cci 400 and rounds using cci #41 using new cases that my Wilson case gage indicates are in spec.

Five out of ten fired using #41 primers

Fifteen out of seventeen fired using CCI 400.

I've taken the bolt a part, it is clean inside, I don't see anything wrong.

Does anyone have any ideas for me on what is going on.


Thanks,

Szumi
