Kind of like this?I use lapua in everything it is made in and would fire form it to others it needed to. I use it in 243, 260, 30-06, used it in 308. IN a pinch can put a 260 into a 243 case or neck up and down 308/243/260 to get what you need. If they just made the 243, 260 and 308 with small rifle primer pockets, I would be in hog heaven. That is what makes the 6x47 lap sooooooo good - small pockets so you can push it.
