I loaded up some .223 rounds for my AR and got them to the range last weekend and threw them over the chrony. Here's the stats LC brass, BL-C(2) 26gr and 27gr with a Hornady FMJ BT 55gr round in it. CCI 400 primers. After shooting off a couple I checked the cases as I always do and then the primers. I noticed that the primer was certainly flatter than I've seen on any of my loads previously (for my Savage 12 VLP), yet speed wise, I was only getting 2600 and 2700 fps (give or take ten or so fps) respectively. One of the things you read/hear is load till you see the pressure signs using the chrony to see if your nearing the max.......but the max of what? In this case, the speeds are nowhere near what I would have expected for a max load....and what would I expect...well certainly something on the high side of 3000 fps and up...or am I just misguided? I immediately suspected that the primers are a little softer than factory ammo because I also threw in a few loads that had gone through the Savage, and they too appeared to have a little flattening, yet I did not notice that when I fired them from the savage. Thoughts? Warnings of dire consequences?
