I love the Lightfields so far. I have a Ithaca 37 20g featherweight deerslayer with rifled barrel, and so far thats the most accurate slug for the gun. Yes it's a pump but when the action is locked forward doesn't rattle. And at 100 yrds can put all 5 shots into the box the slugs came out of. Max range with the Lightfields is about 125- 150 yrds, they drop off pretty quick after that.
