As 500Nitro says, if you buy an Italian or Spanish double rifle and need to sell it, it will be harder. If you can get someone to completely check that Cogswell and it is good that is a fine rifle. There is no difference in felt recoil between a .470 and a .500 IF the gun fits and is the right weight and you hold it properly IMO, my .470 seemed to hit me harder than my .500 but the .500 was made for me, best, Mike
