CCI #34 to #250 comparison

[larryh128]

I'm starting to get down on #250 primers but have quite a few more #34 that I use in my AR-10 loads. I know there is a difference in the cup design in the 2 but my question is whether they both have the same primer mix? I shot a test batch of 300 WSM and accuracy was the same.

Yep, same primer mix. They’re both the magnum blend.
