That's awesome man! Congrats, stay at it... it's addictive! Isaac, that 00 buck shot is probably a little too large for that tight of a choke... providing a poor pattern. See if you can't find some T or F shot that's lead or copper plated. The loads that BHF is talking about are called Dead Coyote made by Hevi-Shot, they're pricey but EXTREMELY deadly.... They aren't safe at 70 yards out of my Benelli!
Well i might go and try a smaller shot size but im not winning to drop thirty bucks on some Dead Coyote yet.
