Hi everybody, New member here.
I have a Savage 110BA in 300 win mag...
I bought a bag ( 50 count ) of new Winchester brass.

Resized them, loaded them up and shot them all. All wen t bang.
*** Reloaded those same rounds and I'm getting sporadic " fail to fires", the primer is hit, but no ignition?


I bought a box of off the shelf 180grain 300 win mag and all went bag.
I've sent it to Savage and they did the same thing, ran 20 rounds of new commercial ammo and they had no issues.
I've had this rifle since 2012 and in the last year+, this has become more and more of an occurrence.
I'm just neck sizing currently. The loads I make are middle of the road loads, not high pressure "hot loads".


Is there something I'm missing as to why this happening? I'm at a loss.

I thank you all in advance for any thoughts you may have to share.
