My bfr had a 7.5 inch barrel (I sold it due to money problems). My 500 S&W has a 10 inch barrel and my 460 S&W has an 8 inch barrel. The bfr has noticeably heavier recoil than my 460 magnum. The 500 has worse recoil when firing the hottest loads, but for the most part, the bfr's recoil is almost always worse. The reason is the weight. The x-frame is quite a bit heavier than the bfr frame. I've never fired a bfr in 500 S&W but I imagine it's quite unpleasant with full powered loads. Of course, the bfr chambered in 500 S&W is their larger, stretched frame so it has to be heavier. That probably helps keep the recoil manageable.
