It sounds like two big issues that keep coming up are bullet selection and practical range. It's true that the vast majority of pds are shot within 300 yards, what Im looking for is the ability to shoot out to 400-500 yards with reasonable expectation that the cartridge is up to the task. I will not be shooting this gun at 1000 yards. Bullet selection goes to the .223 without a doubt. How big of a difference does this make when shooting will be done within above parameters and no very long distance shooting or larger varmints are concerned? Paper and pds are 99% of what this rifle wil be used for. The .223 sounds like the easy choice, but the .204 could be better.
