Greetings AH. This may be subjective, splitting hairs, or just ridiculous, but any feedback appreciated. All being equal in the Firearm ... Out of the Available Factory Ammo, is there a distinct difference in recoil between Kynoch's 535's 2400 fps "I believe" .. Norma's 540 Grain 2400 fps .. Norma's 575's 2198 fps? Thank You!!! I also have Reload's grouped at 50 yards: 600 Grain 2100 fps.? Many Thanks.
