As a new person to the world of target shooting with an AR-15 type of rifle-2 questions. Is the piston type(short stroke) actuation superior to the gas impingement actuation in the AR-15???. Is the .223 inherently more accurate than the .308 cartridge???. Knx
If you have not done so, go to the introductions page and tell us something about yourself. As far as this post goes, tell us more about the kind of shooting you are interested in and the distances, etc. Almost all answers are dependent on that.
The question of piston vs gas is the kind of thing that 15 page long arguments are made of. Each has it's own adherents. GENERALLY speaking, pistons have some advantage in Tactical/CQB shooting where you are going to be putting a lot of rounds down range. For long distance gas should be just fine. You still end up having to do more cleaning than with a bolt.
As to .223 vs .308, it's apples and oranges. Purely from a target shooting perspective, for short distances the advantage often goes to the .223 because it's less expensive and has less recoil. That means more practice time for the $$'s. Beyond a certain point, the heavier .308 has better wind resistance.

Thanks for the advice. Can't seem to get on to the intro page. Would be using AR-15 for target practice(open sights) and load development. Was told by the locals that using a 77gr Sierra,HPBT Match was a good place to start for tight grouping. A common load seemed to be 24 grs/2520 Accurate (ball powder?) or Reloader 15/ 24 grs,velo range 2650-2680 fps and 1:7 or 1:8 twist. Any bbl length favored??Comments appreciated. Tnx
There is no reason to go with a piston-driven AR15. The design doesn't compliment piston systems very well. Ultimately, pistons introduce a long list of problems associated with shoe-horning them into an AR15.
If you think you *need* a piston, buy something designed from the ground up as a piston system. For what its worth, piston-driven rifles vs DI rifles, the difference in reliability between the two is negligible.
