In order to give the subject the respect it deserves, here is a thread on Recoil itself. Here is a link to probably 1 of a 1000 similar links on the recoil of various rifles.

Off course there are so many variables that effect recoil, such as specific rifle build, weight, specific bullet load etc.
However, some have noted on the 458 WM vs Lott thread (p9 onwards), that they, and I am one of them, feel that certain rifles in certain cartridges which are normally smaller than others, have more recoil than the bigger ones. Case in point, my subjective opinion is that my 416 Rigby has more felt recoil, than my 458 Express. Yes it could actually be due all of the reasons above.
For me, I have long thought about why out of my 3 big game rifles, the other being a 375H&H, the 416Rigby has the most felt recoil, which I noted some other have experienced the same thing. The reason I believe, well for me personally is as follows: I am proficient with a 375H&H, shot it for years and comfortable with it. 458 is open sight. 416 Rigby is scoped. As can been seen in some table's, the 416Rigby is very close to recoil energy and velocity to that of say a 458 Lott. I have no issue with recoil, but here comes the "kicker", I believe, subconsciously (for me) the fact that the higher than one expects recoiling 416 Rigby has a scope, which may cause me to join the half moon club, does make it feel like a heavier kicking recoil firearm.
Look forward to hearing what the rest say - let's not make it about facts - the charts gives those, What were your experiences with recoil.
I remember one rifle specifically that had more recoil than I expected an liked, it was a friends pre64 Mod 70 Winchester in 30-06, it still had a steel recoil pad - that thing recoiled like a mule
