Evening all,

I have just purchased an AA S410 classic in .22 FAC and am wondering what the most suitable Ammo for long range target would be. Not Chrono'd it myself yet but was putting out 29 ftlbs apparently.
Hoping to avoid endless testing of a plethora of pellets to get somewhere near.
It is defo a classic Not the FAC Extra.
Many thanks.
