What do you want to kill with your new rifle? Are you looking for a lighter carry rifle that could be used against larger animals in a pinch? I vote for the 9.3X62. For a lighter rifle, you are going to have to compromise on your power level. If you want to hunt DG with it you may want to reconsider. However, I have killed 2 buffalo with its ballistic twin, the 9.3X74R I see you already have some heavier calibers.

Here is a place to get a BIG rifle very lightweight. I just don't know how bad the recoil is.

I hunt, not to kill, but in order not to have played golf....
