Thanks for your response and the offer of primer availability.

I haven't de-primed the 7.62 so your 2.17 measurement will save me some work. As i mentioned to Maca below, as Gunworks have stopped delivering primers, I may just have to sit this one out to see if anything changes....Which still ain't going to solve my problem of how to get them in...
