Man I slay em with the .223 all the time. I wouldn't have a problem at all with the 22 hornet other than the availability and price of the ammo. Ive killed a crap load with a .22 rim fire and recently purchased a marlin ss bb .22 mag bolt gun for hogs. I like the very light rim fires while fishing in the spring around ponds. I throw them over my shoulder, and if a target jumps out, it may get shot. I aim for the ear area and high on the shoulder where it meets the spine is a real hog dropper. Just saw your write up, good luck.
