RE: What shells to try??
They're not making the Xtended Range shells anymore though. They've been replaced with the Xtended Range Supreme Elite line of shells. They cost almost $40 for a box of 10. That's almost approaching the price of Nitros. For a few dollars more I'd definitely go the Nitro route.
I wish they did still make the regular Extended Range though. They patterned awesome in my gun. And they weren't too expensive for a premium shell.
