In loading for my 454Casull, it calls for a SRM primer. In this case, it would seem that a magnum primer would be preferrable. I'm wondering what the difference being Remington 6.5 and 7.5 are. Both are labled small rifle primers but on the 7.5 packet, it says Benchrest. I would think one would say magnum. Anyone know for sure? If so, which?
