Remington or CZ?
I think the Pushfeed is more accurate and that is why Remington and Savage use it more than likely.
Although that may be a side benefit, I think it is cheaper to make, a business decision over accuracy I think...
The CZ is a tank, strong, dependable, and accurate ... the downside depending on model is weight. The controlled-round-feed is played down by push-feed folks, and played up by fans. It is an advantage to have in most cases, working the bolt fast under stress, either danger or a Record Class elk standing before you can cause problems. The CZ is made as a real rifle without corners being cut.
The Remington is usually lighter, accuracy not a factor between the two, especially for field use. Most of the Remingtons I have owned, although custom models for most, have great triggers, but the CZ is good as well, with a set trigger on some CZ models.
You can get calibers in CZ not available in Remington rifles ... .458 Lott, 9.3x62, and many more.
Remington is made in the USA, which is a big thing these days, and work wonderfully in most cases, with good service if they don't.
I love both, but I don't have both in the same calibers, so I choose which one to match what I am doing ... protection in bear or lion country, or shooting deer and elk, etc.
I say buy both, one at a time!
