With a riffled slug barrel and sabots your effective range is almost 75% farther. T roy made a good point in the barrels and sabots are more expensive but not to the extent that he believes they are. I have a Mossberg 500 12 guage. I bought a hastings rifled slug barrel for aprox. 110$. K.O. sabots are 5.99 and shoot well. Lightfields cost 8.99(most expensive, everything was purchased at Dicks Sporting Goods NY)and shoot excelent. If you strech it out to over 150 yards the Lightfields will group better. Where I hunt most of the shoots will be under 85 yards but If I do get a clear lane out to 150 yrds I'll pull the trigger.For this reason I spend a little more on the Lightfields. Realistically speaking one could shop around for a barrel and 3 boxes of shells for around 140$. Two boxes for sighting in the new barrel and one for the season.
