[QUOTE="tim_w, post: 1820049, member: 11132"] You get the same types of case pressure signs. The ejector us worse as the case is quickly ejected and actually swipes the brass off.when its bad enough. As for rims getting riped off etc. Usually that is a timing issues from the extra gas but can happen with in pressure rounds as well if the gas system is not properly tuned for the load. Most ARs are not in ideal tune for the loads they shoot. Find the load you want to shoot then you can tune the gas system around it with a few changes. Typically you can not run quite as high pressure as you can in custom bolt guns as you tend to have to hold looser tolerances for cycling. You can get away with more if you are slow firing. You also gave to account for some vel loss from the gasses used to run the cycling system [/QUOTE]
