Great photo Scenar!
Question for you, do the cold weather misfires also happen with .223 size cartridges? I went out during a recent cold snap (-13 that morning) and took a .223. I didn't get a shot but was thinking as sat there freezing my butt off I should sell my 22-250 as I never use it anymore.
I have been using Winchester brand small rifle primers I bought a few thousand of a couple years ago.
I guess I should test it myself the next time we have a cold snap.
What some here arent getting, is its not just about using sr primers. Its the tiny flash hole some of these manufactures are using to cater to the benchrest crowd. A small rifle primer will work just fine in any small case, like a 223 rem, in damn near any temperature.
