I tested out the 20ga and 12ga Remington’s last year. Groups were very tight at 100 yds with the 220 and the Browning A-bolt 12ga. I still have a couple boxes of the Federal Expanders, so I will be making the switch soon. I’m glad Remington took over the expanders, my supply of the Federals was dwindling down, a buck had to be “Barnes Worthy” before I launched, otherwise all other harvests were with the revolver. I've seen very impressive results in accuracy and penetration with these expanders. Everything I've shot expired within eye site and have blown right thru.
