At my age, added weight in the field is a negative, as I don't enjoy lugging things around I don't need. For a field reload when hunting, I much prefer hickory. I can't think of a reason I want one with a steel/brass core. For range use, I'll use the SS rod with a bore guide.
There is a person who has a running ad in Muzzle Blasts classified who sells very nice hickory ramrods. You'll need to buy 10 or so, that they can be bundled together for shipping, but sizes can be mixed. I suppose you could shatter a wooden rod when reloading by grabbing it 2' above the muzzle and bending it way off-center. Just because someone thought of it doesn't mean I need one. Your needs may be different than mine!
