I had a 220, accuracy was typically good but at $4 every trigger pull range time got expensive. The one flaw with that gun is that it does not come with iron sights so you are forced to buy a scope and at close range you may not want one anyway. The Browning A-Bolt slugger comes with iron sights but at an extra costs which offsets the price of the scope, unfortunately it only comes in 12G, now if they made that gun in 20......
If you google a ballistics calculator (

I now use a smooth-bore A5 in 12G with iron sights for my range time, I get good (4 inch group at 50 yrds) performance with the Federal Truball and would hunt with it if keeping the distance under 50yrds.
