I was at my gun shop today picking up some cleaning supplies. A "gentleman" was telling me that a double rifle (he shoots a 470 Nitro)has a different type of recoil than a bolt rifle does and is more punishing. Does anybody have experience shooting a 460 weatherby(factory loads 500 grain) and 577 Nitro? The reason I'm asking is because I'm talking to Butch Searcy about having my 577 weight 11 pounds vs 13 pounds. I shoot 20 rounds factory loads per range practice session. Thank you for your help!..steve
