Even with the muzzle break its still rough?
Maybe I misunderstood your question.
Is recoil with the 460 with full house loads & a muzzle break really "rough"? Not to me, but that's subjective. I shot a 15" Encore with factory brake in 450 Marlin with full house loads for a couple of years & didn't mind. Some who tried it once didn't want to shoot it a 2nd time. Subjective.
You asked how it compares to a 35 Rem in the same length, both with brakes right? The 35 Rem is basically "recoil free" in that configuration. Very pleasent for most anyone. The 460 still has very noticable recoil. You will definetly know something happened when you touch it off! Rough? Not to me, but the difference (That was the original question right?) between the 2 is night & day.
