Recoil is heavy, far more than I had expected and more than the .458s and similar I have used, and I have had many down to eight pounds, including Ruger #1s in .500 NE # 1/4" and all the big .45s including .460 Wby at nine pounds. I would compare this double recoil to that of the nine pound .500 with 650 casts at 2100. It could be a bit lighter, I have not shot it since last fall. I will have to get these 650s over the chronograph the first chance I get.
I will try to get some pictures posted tomorrow.
