Which would you prefer to own and why?
My list of preferable CRF rifles was following:
Winchester m70
Zastava m70
ZKK 602
CZ 550
I was looking for 375 H&H
Winchester is medium length action, and holds 3 rounds in magazine, safety is winchester type on the bolt. Zastava is thumb safety blocking the trigger, medium action, 3 round mag, safety push fwd to fire.
ZKK 602 and CZ 550 are magnum lenght action. thumb safety, large magazine capacity. ZKK 602 takes 6 rounds in magazine, plus one in chamber. Safety is push back to fire ZKK. Barrel is not free floating.
CZ 550 as per specs should take 5 rounds in mag.
When I was looking for rifle, and 375 is hard to find at my place, I would take any of the 4 I mentioned, and then I would do de - bugging at gunsmith as necessary.
But I inclinded toward magnum lenght action
ZKK 602 is a bit heavier, and this tames recoil. Another advantage. (I tried Zastava 375 HH at the range, and recoil is stronger when compared to ZKK)
On the end I had a chance to buy ZKK 602, I took it, changed the trigger and safety (I installed Winchester type safety and back market trigger from Wayne of American hunting rifles).
Rifle is now 1.5 MOA average. For hunting purposes has shown OK. I am more then happy, took it to Africa already twice.
I have seen few winchesters m70 around of post - 1990 production, made in Portugal (not in 375) and overall impression is they are better in fit and finish then ZKK and CZ, and even more then Zastava.
Bad news: ZKK 602 and CZ 550 are phased out, available on 2nd hand market only, winchester and zastava are still produced, you can buy new ones.
