They do make the 30 grain pellets, cabelas will for sure have it. I got mine at scheels so yours should carry it too as well if you have one. I do use 2 fiftys and 1 thirty and it works really well. I took a 8 point buck at 198 paces and it performed flawlessly, including 3 other does and all were one shot one kills without any going farther than 10 yards.
