Gents:

Are CCI 250 primers appropriate for the 375 H&H?

Absolutely.

Why would you think them NOT appropriate? They're large size and they're magnum strength.

That's strange, I ditected no negative inuendo! Where did the "think them not" come from? negative approach syndrome? roger

I'm not afflicted with any syndrome that I'm aware of. Thanks for your concern. Or are you sore about my 'beer goggle' remark in the Oehler thread?

This group of 9 words was so simplistic of a question, I thought, in the best Paul Harvey vein, that there had to be the rest of the story?

Actually I thought the beer goggle remark was rather clever. roger

onefunzr2,

I simply asked because as I am learning about this stuff I prefer not to assume too much. So, while my question may have seemed simplistic and obvious to you perhaps you can appreciate my naivete and cut me a break.

How about it??

Done. After all, every one of us was a beginner at one point.
