Re: .284 win
If recoil is your issue, build a .300 of some sort and put a break on it. You will have a long range rig for target shooting and two options when hunting, one for very long range and one for mid/short range. Either that or get something smaller than a .284 and use that for paper and use the 7 mag for hunting, just with a limit of less than what you are looking for. I don't think you are going to see a real difference in the .284 vs the 7 mag in recoil.
