I started out deer hunting many years ago with a pair of Swedish Mausers in 6.5x55 shooting 129 grain Hornady jacketed bullets over a load of IMR-4350. It is a relatively flat shooting cartridge with minimal recoil, especially in the 29" barrel version I have. The carbine version kicks a little harder, but not really noticeably. And I always got my deer with that caliber. Later, when I tried cast projectiles in it, because of the fast barrel twist, I could only shoot real mellow loads not useful for deer hunting. But I killed a bunch of squirrels with it with cast. Accuracy was outstanding for the 129 grain Hornady's and I killed a deer with the 29" barreled version at about 400 yards using the open sights on the gun. I don't use the rifle much anymore since I mostly shoot cast projectiles and there are far more appropriate calibers for them (45-70).
