With practice, its a 250 yard gun.
i shoot my 45 with a 200 grain SST to 200 with good results. I don't have a range further.
110 of BH 209, Wichester 209, Harvester smooth blue.
Out of the 50 it will shoot most anything well. I like 300 grain bullets and have used several but it likes the .452 diameter with a Harvester long smooth black sabot.
