Thanks for the replies. I think 30 ft lbs would be enough for what I need. I can use reduced velocity rimfire ammo if I'm shooting in a situation where I need more range, say 40-50 ft lbs. problem with these is, they carry too much energy to shoot into trees. I'm looking at safely toppling lofty corvids and squirrels but with more authority that a 12 ft lbs air rifle,where a rimfire couldn't be used. I've used a .25 at 12 ft lbs but I thought they might be more useful than a .22 at FAC levels. Just wondered how the two compared at these power levels. Thanks.
