I purchased my first big game rifle the summer of 1952, It was a Winchester Mdl 70 270 Win. I used for shooting prairie dogs , pronghorn, mule deer, elk and other critters. A few years latter I got a 222 Rem Sako varmint rifle. Some time after getting the 222 Rem I started to try to find the PERFECT varmint , and big game rifles. Sofare I have tried out the 17 HM2, 17 HMR, 17 Fireball, 17 Remington, 204 Ruger, 22LR, 22WMR, 22 Hornet, 221 Fireball, 222 Rem, 223 Rem, 22-250 Rem, 220 Swift, 243 Win, 6MM Rem, 257 Roberts, 25-06, 264 Win Mag, 270 Win, 30-30 WCF, 308 Win , 30-06 Sp,308 Norna Mag, and 340 Weatherby Mag. -- Most are bolt action rifles but I have pump, semi auto and lever guns for wools hunting. I have had fun looking for the perfect rifle but None are perfect for all hunting in the U.S.A. But with reloads and selecting the bullet to match the game I could shot all the game with my old 270 . Good luck , Im still looking.
