In 2008 I took a nice mule deer buck with the Swede.
And I tagged an antelope doe for the freezer with it.
In 2009 I used my Rem. 700 Classic 6.5X55 with Leupold FX4 scope to take an antelope buck (no picture ), fork horn mule deer, and spike elk in three ½ day hunts near my home in SE Wyoming. It was a charmed season, for sure.
Ammo was standard Federal 140 gr. for the antelope and deer. The elk fell to a handload using Hornady 160 gr. RN Interlock. The antelope and deer were 200 yard(+ or -) shots. The elk was less than 50 yards away when shot.
2010 was a tough year. My only harvest was a white tail doe with the Swede.
I am convinced that the 6.5X55 is greatly under appreciated and can handle all of my hunting needs as long as I do my part. I was not impressed with the performance of the 160 gr. RN bullet on that little elk. My modern Rem. 700 rifle shoots 140 gr. ammo the best. Going forward I will stick with 140 gr. bullet in factory loads or handloads for all my 6.5X55 hunting ammo, including elk (and moose if I ever draw the tag).
