Rebarrel a cz527

[Bassfish1952]

Should probably look at websites or call the usual suspects...
mcGowen, preferred barrels, x-caliber, others... the key besides who actually makes CZ barrels, will be the lead time.  Lead times can be 12-16-24 weeks so, so best get figurin' quickly.  I don't recall seeing which ones actually make CZ barrels however.
As to specs, there are some fairly standard ones, like 7.5 twist rate (some folks go for 7 tw), I personally like the 20" in a bolt action.  I'm working up some 100 gr Tgk's at high 2700's, easily shootable for kids as well.  good for beyond even 250.  103 Eldx works too, as some 95 berger's if you want.  Bullet selection is not always what you want but what you can get.
Talking about rifles you might want to think on getting a Uintah bolt-action upper, which goes on any spec AR15 lower.  The cost for this upper will be ~comparable to your custom barrel and you could get it in and practice with it much sooner.  That's the one I'm working up the Tgk's on.  Super nice for the money.

Thanks right now I just want a good barrel for the cz and a place that will install. I have a lot of lead time this will be an additional rifle for me and the great grandkid is due in a couple of months so maybe 8 to 10 years on them (now have 2 on the way ) I have heard of Pac-Nor but none of the ones you mentioned I'll get on checking them out
And I have picked Hornady ammo so will keep an eye out for some as I go along
