Norma Tipstrike Varmint 243 Winchester 76gr PT Rifle Ammo - 20 Rounds - The .243 Win. was originally a wildcat designed by Warren Page who necked down the .308 case in the early fifties. The goal was to make a light deer rifle which would still have the advantages of the high-velocity .22-calibers for varmint hunting. In 1955 Winchester made it a commercial round. The .243 is a very popular round all over the world for hunting medium sized game, probably due to its flat trajectory and very mild recoil. For small game and varmint hunting bullets in the 70-85 grain range are suitable, but normally the expansion of theses bullets are too rapid to give the necessary penetration needed for quick kill on larger game from pronghorn antelope and upwards.
