That is the gun that I was looking for when I bought mine. Couldn't find one, so I bought a marlin that looks identical. Oh and I saved about $100 too. The 20grs shoot great, but if you want to use the dial adjustment you will need to compensate for the difference as your scope is calibrated for 17grs. I have the same scope. Your poi should be close under 100 yrds but anything further you will have to experiment. The hornadays seem to shoot the best regardless of the gun.

BTW Very nice gun...Im jealous.
