I like my CZ 452 American 16" threaded bbl. 5 or 10 rnd mags, light and quiet
Their current offering is the 455 synthetic threaded bbl. They also offer a 455 combo with user changeable 22lr and 17HMR bbls. Great guns and very accurate. The 455 varmint is good if you don't carry it around a lot. Any of those you mention are also nice rifles.
