Sharp,

Paul is right on with his assessment. I'd grab an Improved cylinder choke and have at it. I've had good luck with the winchester super-x slugs in 3 different model guns (Remington, Ithaca, Winchester).The 2 3/4 inch shells have plenty of power behind them, so I wouldn't mess with the 3" slugs.As Paul alluded to, I have an 1100 20 gauge that will clover leaf remington sluggers at 50 yds through a skeet choked barrel. The problem is that it shoots 4 inches low and 3 inches to the right. The solution was a set of $50 clamp on adjustable fiber optic sights (Half the price of a used 1187 slug barrel). Iron sights only get you out to about 75 yds for accurate shooting. I have 2 scoped 12 guages and they produce excellent groups at 100 yds. So accuracy can be obtained for that far out but it costs $. Long story short, don't be afraid to try what you have, but if it ain't working look for a used slug barrel and save the headache.
