I would expect a big difference between your 25-06 & the 450/400. My heaviest recoiling single shot is probably a 338-06 JDJ. However, it has a brake on it. The 375 JDJ without a brake and with 270 gr bullets produces more felt recoil to me.
In revolvers currently 454s. However, I am awaiting the 475 from Rod & the 500 WE from Bob.
I have fired both the 500 S&W and 50 AK in encores and the 500 S&W in a BFR. Without brakes they will get your attention.
