Thinking of picking up a GSR as my first rifle. This would be for range fun, not hunting. I'm a lefty and I really want a bolt action with iron sights, so the GSR is an obvious choice. I can't decide on the caliber though. The .308 is iconic for this genre of rifle, and candidly a very powerful round is fun. But if it kicks enough that it can be punishing, the .223 would make a lot more practical sense at the range. Like with my SP101, shooting off some .357 Magnum is fun, but I'm glad I can spend most of the afternoon with .38 Spl, and wouldn't practice nearly as much if .357 was the only option. Plus ammo costs weighs in favor of the .223. Anyone have experience with either and wants to weigh in?
