This isn't long range, but it's reloading related. I'm sitting at the reloading bench this morning loading some 45 ACP rounds. I start priming the cases and at about the third one I can't get the primer to start into the primer pocket. I pull it out of the shell holder to check for problems, and I realize it has a small primer pocket. The brass is some I picked up from the range last weekend. I start checking the cases and out of the 200 or so, over half are Federal cases with the small primer pockets. Due to the fact that I already have a bunch of 45s loaded, I haven't reloaded 45s in several years. How long has Federal been making 45 ACP brass with small primers? Are they doing the same with any other calibers? What effect, if any, will it have on reloading data?
