Not sure I want to handle the recoil of 4 pellets and I certainly have no interest if it can't reliably ignite a reasonable BH 209. Using Bob Parker's Ballistic Extremes or Match Hunter it should perform well. My personal limit is 250 yards and using 110 gr of BH 209 and Hornady SST 300 gr or Harvester's Scorpion PT Gold 300gr I get very good accuracy at 250 yds. I assume it will not require a 4473 form to acquire.
