Andy I used to shoot the savage pen. but I lost sight of a deer one eveing in the small sight window.I use a toxionics sniper,It has a pendulum plus fix pins. no problems so far.I live in the hill county and were I practice is hilley. On the ground or in air its dead on. I hate judging distance. MY freand shoots the impact and likes it. I want to try the new,savage super max bigger sight window.
