There are 6 6mm guns/barrels(6br,15" 243 Striker,6/ 284, and three other 243s) in the safe that are very accurate.
If I had to use the 243 it would be with R22 and a 105Amax or the 95 grain Nosler Partition but there are better rounds in the safe like the 6.5x55,6.5/284,7Mag and 30-06 to hunt deer with. Sure the 243 will work (so would a 22lr for that matter-if legal) but prefer the added cushon of error that the bigger rounds deliver in my less than perfect world.
