The old 94s are the absolute worst for me, but then anything with the old style curved "rifle" butt is painful, unless everything is done just right, and then its only uncomfortable. For me. I never could understand why that shape was popular, other than after you fired your one shot from your flintlock, it made a better war club than a "shotgun" style buttstock.
We grew up in the 50's and 60's shooting 03's, K98's, M1's/M14's, etc, and didnt know they were supposed to kick. We didnt know any different or better, and it was what it was, and you were taught how to properly and comfortably shoot them.
We used to shoot them in our tee shirts too, steel butt plates and all, and rarely a bruise the next day.
A hot loaded 30-06 with a steel butt plate doesn't kick much at all. A 30-30 doesn't kick enough to even notice.
When I purchased my Mosin's, I was told by many that they kicked like a mule.
