I appreciate the input from all who responded to my question. Stopped by Cabela's to look at ammo options. No bismuth or tungsten matrix in stock. No Classic Doubles. Lotsa lead and steel. NickD90, you're right about a new gun, or at least a new barrel being the best long term solution. You would pay for a barrel quickly, when the alternative is shooting $4.00 a shell non-toxics.

Add an $80 Westside pheasant permit and $4.00 per gallon gas to the cost of ammo; soon only ascot wearing hunters will be able to participate in the sport. Hopefully, they'll use the hackle of their kill to tie Carey Specials...
