I think they are 240 or 245 grain. I went back to Gander Mountain to buy a few other sizes since they were so cheap but they were closed when I got there. I don't know when I will be able to make the trip again. It seems to shoot nice, I didn't have a steady rest and was floating around the target with the extremely high winds. When I got the scope close the last two shots were within a couple inches right on the bullseye. I know it's going to be alot better when I build a shooting bench and play with the powder amounts.
