Hi Whip, buying smart one can shoot the CO2 pellet guns for ~$0.02/shot. I buy 40 C02 cartridges for ~$20 and 500 pellets for ~$5.60. The Crosman 2240 gets 50 shots from a CO2 cartridge. There are a lot of YouTube videos on how to optimize performance. I had my 2240 with shoulder stock down in the basement shooting this morning. That rig is so accurate that there is little challenge shooting it at 50ft, the pellets almost go shooting offhand in the same hole. That shoulder stock rig will be better put to use at 50yds, not 50ft. It will probably be the 2240 without shoulder stock that will get the most use in my basement this winter.
What's nice about using a pellet handgun regularly is that one's shooting skills can stay sharp, even in bad outside weather.
If you like screwing around with guns, doing mods to the Crosman 2240 yields benefits. Getting a light smooth trigger pull is little more than polishing the sear and changing the trigger spring. Put a longer barrel and you get more pellet energy. Instead of the stock 7.5" barrel, a 14.5" barrel will raise pellet energy ~50% with a pellet velocity of 550fps.
Regards,
Richard
