.30-30 Winchester Super 14 and .45-70 Govt. Super 16. The .45-70 barrel is Magnaported, but tapered. I don't recommend it unless you're simply shooting 405s, but what fun is that? 300 gr Remingtons are interesting
to say the least. The .30-30, OTOH, is simply fun with a capital f. Always wanted a .223 Super 14 barrel. I'll have one someday.
