Hi greyhound 1
Mine is very accurate with Air Arms fields, and also it produces the most power with them, accuracey wise the barrel on the 410 isnt very pellet fussy, but what ive found is the power can be down quite a bit with certain pellets, the Bisley magnum in mine is down about 2 ft lb, R W S hollow points, are down a good 1 ft lb . There are other pellets thats more or less the same as the A/A fields, that will perform more or less just as well ( R W S super fields £1 a tin less). Hope this helps.
