Anyone willing to share your experience with the Beeman AR2078A CO2 rifle? I just ordered one up in .22 and am hoping for tips and tricks from fellow AGN members. This is the first CO2 rifle I've ever owned, bought for use on my 10m indoor range (i.e. my garage) in the long Winter months of Northern Indiana. I've had CO2 pistols before and know a little about their feeding and care (Pellgun oil drops, clearing the CO2 out before storage) but there's always more to learn. Tips on 10m shooting are also welcome.
