.243 Winchester Brass Cartridge Cases
According to Derek Peterson, president of Peterson Cartridge, “Lots of shooters still use .243 Winchester for long-distance and competition shooting. And many of these shooters want it in Small Rifle primer (SRP). But no one else makes it in SRP. Some shooters are even going to the trouble of buying Lapua .308s in SRP and necking them down to .243. But of course that causes a doughnut at the base of the neck, requiring the neck to be turned down. Now people can buy Peterson match-grade .243 Winchester in SRP and save the labor.”
Peterson Cartridge has also observed the increase in popularity of long-distance hunting. And of course the .243 Win is a good long-distance hunting round. Most hunters load using Large Rifle primers (LRP). So Peterson now makes .243s in LRP also.
