I like the Marlin .17hmr. Tossed a $50 Tasco 3x9x40 on it. Shoots great. Will put 3 rounds in a clover leaf pattern touching, consistently @ 100. I shoot the Hornaday 17gr loads the most, though I have tried all kinds of brands, the zero dosen't change enough to worry about. Even the 20gr loads shoot very similarly. They are so very accurate, and fun!
