I have a CCZ550 Safari in 416 Rigby. They are the best value for the money in the Safari class of rifles. Better quality than the competition at almost half the price. That being said, some people say that it's a good idea to either reinforce the stock or replace it with a synthetic or laminated one. That goes for wooden stocks of any manufacturer in these heavy calibers. I've not had any problems with mine, but haven't shot it a whole lot. Recoil is a bit much. If you're doing some serious dangerous game hunting with it, you'll probably put several hundred round through it to test reliability. That should either crack the stock or not. I haven't used mine on anything dangerous yet, but plan on a Cape Buffalo trip one of these days, (living in the middle east puts me very close to Africa). I'll probably do something about the stock before making this hunt, better safe than very sorry.
Finish and accuracy are superb on this rifle and a CZ550 in 243 Win. I have.
