I noticed that Graf's had Privi 7.65 Mauser (Argentine) brass on sale, so I took the plunge and ordered 100. I've used Privi in several of my older military calibers and was always satisfied. They arrived several days later, nice and shiney and ready to go.
The first thing I checked was chambering in my 1909 carbine...no FL needed, so I gleefully began priming and that's where I ran into trouble. I was using a Lyman 310 tool (because I'm aquiring a set of dies for each military caliber I shoot) and was suprised at the amount of force required to seat each primer. I set up my ram prime in my Rock Chucker for a little more "oomph" and promptly distorted the rims on two cases in a row. At that point I stopped and set up my primer pocket swager and began running the cases through it. Each and every one went in easily so the pocket dimensions appear to be normal. I also reamed each pocket and made a slight bevel at the mouth of each pocket, thinking perhaps there was an unseen ridge. It still required a fair amount of force to seat each primer, almost like there was a small taper. I finally began seating each primer by rotating the cases and seating in stages, finally getting the primers level with the base.
I'm a little bewildered by this, as the primers are older CCI 200's that behave normally in every other case I've used them in. I'm hoping with use the pockets will loosen up just bit, but has anyone else run into this or have any suggestions?
