Wow, ok, gotcha. Thanks for the info, I don't wan't to destroy my reciever this quickly.
I did hit the range today. Using 9grs of WC820 and a hardcast 200gr bullet I was getting in the neighborhood of 1180fps, but not cycling even with the CAR buffer spring. So what do I do now? I have to drop the powder charge, I will be trying 8grs next but what about the cycling? Do I get an extra CAR spring and cutting coils?
ETA,
I just took apart and removed the internal (rifle type) buffer weights, just over 3 1/2 ounces. Do you think if I run it this way it would help cycling with subsonics? Of course for supersonics I would have a standard buffer to drop in.
