Those bloody hornets!
I'm can see a second coming in the 22 hornet as time goes by, looking at adding one myself in time, just such an awkward size bolt face and mag length to cater for.
I did wonder if the Howa mini action could cater for it, but its probably more work than its worth trying to convert, may as well just get one already made from CZ/Weihrauch/Annie, shame the mags are a little short for future bullet choice.
