I'm upgrading from my Gamo Shadow 1000 in .177 and buying a better springer. I'm thinking of pulling the trigger on a Beeman R9 and need help choosing the optimal caliber. I shoot 50% paper targets, metal plinkers, pop cans, clay discs and 50% small game/pest control with chipmunks, raccoons, and possums.I hope to hear from some Beeman R9 users/owners and what you experiences are.
the only advantage a .177 would have on a .20 is a little flatter trajectory and a crazy variety of pellets. I would recommend a .20 caliber first, as it works great because it has a lot more knock down out to 50 plus yards, and the extra weight also helps bucking the wind deflection. The extra weight satisfies the can blasting hooligan on me (it hits hard, no joke...), the extra face area of a pellet helps disperse impact energy better (the bigger the better, no questions asked...). If you do mostly pesting i would even recommend a .22... just because of the larger pellet variety... but as a all around rifle the .20 is got a lot going on...
