Update on 527 carbine..I went ahead and got the 762 carbine. It came as a 2018 model, fiber-optic iron sights and new oiled wood stock treatment. Thoughts? Dandy rifle. Handles very nicely, bolt smoothed right out after about 100 rounds. Good accuracy with iron sights, me being the downside in the equation. Currently using Barnaul and Norinco non-corrosive commercial production ammunition. It seems to like the Norinco better.
Matter of fact I like the CZ so much I went ahead and got a 527 223 varmint as well. I put a Leupold 3-9x40 with stock cz med rings and a bipod on it.
I'm currently in the process of finding a cheap ( I don't reload ) brand of ammunition for it. It has a 1/9 twist and is showing best results with PMC Bronze at 55gr fmj. It doesn't seem to like the heavier offerings though. Green-tips at 62 grs pattern not group for me. Anything heavier seems erratic. Perhaps more experimentation. Hornady V-Max 55 gr is producing 5 holes in about 1/2 in or less at 50 and 5 in under 1 inch at 100 yds.
Stocked up on that.
Overall, as far as I'm concerned with what little experience I have, I'm quite impressed with both rifles. Fit and finish are excellent ( stock on the 762 still in one piece by the way ) on both.
Performance is right up there with zero help from me.
Thanks for your comments gents, made the decision easier.
Try the Winchester White Box 40 round pack .223 ammo... it has been very accurate in all of the rifles that we have tried it in... also does a good job on coyotes. You have a nice pair of rifles there for fun shooting and plinking... up to short range deer with good bullets... although for hunting it helps to reload. In your 7.62, 30.0 grains of CFE-BLK with 123/125/130 grain bullets is usually perfect for accuracy and sub-100 yard energy on deer.
