I've had a Beeman break-barrel air rifle for a few years, which I shoot infrequently in my garage. I think it's an RS2, but I only have the .177 barrel. A few months ago, I added a Crosman 1077 because they're cheap and I wanted a repeater to practice shooting from rice-paddy-prone position.
Naturally, I wondered how much difference there is between them in power, in case I have to harvest the local squirrels or crows for food after the Cascadian Subduction Zone rips loose again and I run out of neighbors. Shooting into the end grain of a block of red cedar (pretty much North America's softest wood) showed that pointed pellets from the Crosman would barely bury themselves in the wood, while the Beeman left at least a 1/2" deep hole behind them.
I found a couple other targets of opportunity in my pocket, and stuck them to the block with blue masking tape. The Crosman target is on the left. IIRC, starting with a new CO2 cylinder at about 65 degrees, that was either the second or third shot that finally found Lincoln's jaw. With the Beeman I winged it right on the edge the first time (barely visible damage) then flipped it over and did better on the architecture.
I guess I'll choose the Beeman if I decide to hunt anything bigger than a Song Sparrow.
