The Browning is very cheap but you would have to be a reloader to consider it . If you bought enough brass up front to allow you to wear out a couple of barrels and then throw the action away it may be alright . Seems like the WSSM's are going the same way as the Dodo and brass may become very scarce .
Also beware that stainless Brownings have a reputation for buggering up the action threads when barrels are unscrewed .
If a tight budget is the problem there are certainly cheaper .223's around than the CZ .
Savage make a model 16FSS in stainless and a model 11F in blued with pillar bedding and accutrigger .Nothing more to spend and have a great reputation for accuracy . Weatherby and Ruger also make well priced .223's .
Nothing against CZ . I have a CZ 527 and like it a lot . I spent an extra $160 to have it bedded and the trigger smoothed up though .
