Get in touch with Bill Hindgardner of 50/50 or Dan K to get the newest plug that Bill came out with for 50/50. I believe it can also be used for RBA.
Slick and Don are correct on your targets and the scoring, the ARA with its worst edge is a tough target. Don't get me wrong you are doing great for the few targets you have shot with your new gun. The more you shoot the better you get, good luck in the future...Keep on Shooting.
