I own a Weatherby Mark V Sporter .340 Wby. Mag. with a Pentax Lightseeker II 4-16x44, and I will never sell it. I push a 250 gr. Barnes XFB 3062 f/s, 5204 ft/lb, and.408" three shot group at 100m. It took about 100 rounds to become accustom to its recoil which was donein a two daybreak in period. Just make sure your scope has enough eye relief. Good luck.
