I've been shooting one since 1972. I use 30 grains at 25 and 50 yards and 60 grains at 100 yards, all 3F, Douglas barrel. Won my first, first place ribbon at our local club with it. Once killed a ground hog at 125 yards using 70 grains of 3F. I have had more fun shooting this rifle than all my others over the years. Including my .45's, .54's and my current .58. Great game guns and great fun guns, cheap to shoot.
