I think you'll love it.
Nearly 20 yrs ago now, I bought a Ruger 77 MkII in x39mm. It is an odd model, stainless, slim 20" bbl, and boat paddle stock. It was my first ( and remains only) stainless steel long gun. On to it, I screwed a Leupold 2-7x. My plan was to have bamaboy use it as a deer rifle with its light recoil. I liked the idea that it could shoot affordable ammo too. Things have not quite worked out the way I thought, but it was all for the better.
The boy killed two deer with the x39mm Ruger, , moved to a .243 that belonged to his Grandad, and now likes .308. I started to load for the Ruger bolt x39mm almost immediately, and it has never had a round of steel case through it. I hunt it a great deal, as it is nearly impervious to bad weather, shrugs off rough handling, and is feather light to boot. I've killed a number of deer with it, including the biggest I've ever taken... at 19 steps ....and never shot it at deer past 60 yds or so. I've found the x39mm to have plenty of punch as long as you don't try and stretch the range with it. In the woods, under 100 yds, it kills just fine. I hunt a Mini30 for deer as well, and occasionally even a scout scoped AK, but I've not taken a deer with the AK.
Scope wise, the 2-7x on the bolt rifle is great, but I could get by with a top end, small bell 4x as well. The Mini wears a 1-4x Leupold which is OK too.
Seems silly to mount a honkin' big scope on a tidy rifle.
I zero all 3 rifles "on" at 100, and don't expect to ever shoot past 150 (at game) with them. Been all over the map with projectiles, and am currently shooting reloads using Hornady 123 gr SST's, which I posted a report on a few years back. That ammo, BTW, is available over the counter in a steel case from Hornady and is fairly priced. I've been looking at the Hornady 135 gr (.308 dia) FTX slug too for in reloads with the bolt rifle. But I give up some accuracy with the .308 slugs as opposed to .310, especially in the bolt rifle (Mini30 and AK don't give enough accuracy to detect the difference). The heavier 150 gr slugs are just a bit slow to suit me,but I have fooled with 150 gr (.308 dia) FN .30-30 type slugs in both the Mini and the bolt rifle , both running 1800-1900 fps from the short barrels.
It is not a rompin", stompin', fire breather byt the x39mm does about 75% of what I need a rifle to do. The CZ rifles get good reports and I bet you'll be well satisfied with yours when you get one.
