I don't know a whole lot about your rifle, but I do have a quick fix to your woes. Once you're sure you're sighted in- get off the bench. I don't know why, but nothing hurts as bad as bench shooting. Learn good practical positions such as sitting, prone, and standing.
You can (with practice) produce nearly as good groupings from a solid slung in sitting position as you can from the bench (I said "nearly"). And from the prone- make that "more nearly". Standing is another story. It's a shooters high achievement to claim he's perfectly satisfied with his standing groupings/scores. But any way, try a few rounds away from the bench and you'll better see that the recoil isn't so bad after all.

I'm going to use the words "clip" and "Long Colt" every chance I get. It grinds my gears to see new members attacked when we all know dang good and well what's being refered to.
