Hello Jason, I like yourself am new to the Parker World and received my Parker as a gift from my father who got it from his. the info i have for RST is
www.RSTSHELLS.com, 570-553-1651. I got some shells from them and shot mine one weekend about 3 months ago. i now own some very nice and lonesome O/U. i shoot sporting clays every weekend, and have shot the Parker every weekend since and even aquired another one. Good luck on your decision..... i would keep it.
