I literally bruised my shoulder when I initially sighted in my 30 06. The length of pull was too short for me and the recoil pad was pretty hard. With a softer pad, which also fixed the length of pull, it is reasonably comfortable to shoot. With scope it weighs less than 8 lbs. I think the biggest I've fired was a 30-378 Weatherby shooting 180 grain at 3500 fps. It was heavier (but a sporter) and was not uncomfortable. But the stock fit me reasonably well.
I said this to suggest that having the gun fit you is important to managing recoil so that it doesn't become unpleasant. Weight of the gun also makes a big difference. My suggestion is to make sure the length of pull is good for you and the height of the comb is good for you and if it still seems to be more recoil than you want, consider adding some weight. There are mercury devices that add weight and also spread the recoil out some, for instance, that can be added to the stock. If the stock is hollow, it is easy to add some sand or bird shot to add weight. While there are a few PCPs that go over 1000 fpe, that is still pretty low for a PB deer rifle.
