Have never seen Kranks list .17 hornet brass, yes their value .17 bullets are very good, had a dozen rabbits last night with them. The OP asked for .17 hornet brass obviously not looking to convert .22 hornet brass to .17
it’s not quite as simple as you suggest, I know i have done quite a few. It needs trimming , it needs annealing and yes resizing to 17 then fire forming, full length resizing, trimming again and annealing again.
