Noisey (spook stuff sometimes), ammo expensive (200 rounds £50 compared to £14 for .22), messy even if your head shooting them, like a blood bath in the back of vehicle, once you get any numbers in there , and they don't seem any were as consistent as a .22 with grouping. Not for me anyway, .22 will do it all, if I want long range crows I'll decoy the fookers with a scatter gun
If your looking for a good gun, get an anschutz carbine rifle, standard or thumbhole, now they are sweet
