You're good to go as is. When they were first introduced, I decided to add a 243WSSM to my pack for those long shots at coyotes that had held up long on the ranches I did ADC for. Dang ranch hands would take pot shots at them daily making my job harder. Anyway, I bought a Win Mod 70 243WSSM too, but mine is a featherweight deluxe. I wanted the sporter taper barrel to keep the rig light for easy carry as I trekked around the ranches and the extra oomph for the ranges that were now 3-500 yards. As luck would have it, a two story fall ended my "trekking" days and stopped my doing ADC before I ever used the 243WSSM. Still have it NIB... and am still itching to use it.
