Hello everybody. I'm new to these forums as of a month or so ago. I have handloaded off and on for years, but as of last summer I have gotten much more serious about finding the best loads for my various rifles. Lately I have been trying to get the 100 grain Speer spitzer for my 25-06 dialed in. I loaded a box using half IMR 4831 and half IMR 7828, each with both of the powder charges listed in the Speer 13 edition. After shooting the slower loads with each powder with no pressure issue indicators on the primers, I proceeded to the hotter loads. These also fired with no problems, and I had really good groups with the compressed load of 60 grains of 7828 in particular. When I went to seat primers in the empties just now, I found that the primers sort of bind up and then pop in to the pocket, which I have never had happen before in any caliber. They seemed to shave a little crescent of brass off of the pocket too, which could be recovered from the little primer cup on my press after the primer seated. Anybody ever had this happen?
