If you are wanting any of the rabbit to EAT that you shoot with any of these tiny but quite destructive rounds inside of 100yds or so be aware that you will absolutely need to be truly accurate with your bullet placement. NOT something one initially thinks of here with such tiny rounds (more the game animal bullet type predicament, but inside of that kind of range the .17 calibers (ANY .17 cartridge) will likely fragment inside of the critter's small body and leave tiny flecks of the lead core all over the insides around the bullet path and for a bit of distance to the sides. Similar CAN happen with the .22 Hornet, but more likely is that the rabbit will be just a nasty mess, certainly with a body shot, depending on the bullet construction used.All three are rather different and a lot will depend on the use you're putting them to. The17HMR is an excellent 125-yard rabbit round and good for a fox out to 75 yards or so. The 22 Hornet has a bit of a loopy trajectory but, in the right hands will stop a fox out to 175 yards. It's a bit rough on rabbits though, should you want them for selling. Easy to load for and gives excellent results with Lil Gun.
The 17 Hornet is a brilliant round for long-distance rabbiting out to 200 yards at least in the right conditions. and I've dropped foxes at 150 yards but also had the odd runner. A bit of a fiddle to reload for but can be done.
I've got all three but I find I'm using my 204 Ruger more and more, but both the 17Hornet and the 204 Ruger can be very destructive on rabbits!
Research probably more reliable for answer. First idea is to hang on to HMR until the replacement is successful. I had a 17 hornet - influenced by latest new thing, forums, you tube etc. Sold it as didn't offer anything I couldn't do with 17HMR/20 practical/.223Been thinking about selling my hmr and getting a 22 hornet or a 17 hornet as I reload and think this may be a better option any ideas
