    My 527 is chambered in 7.62 x39 what about new barrel
    and 6.5 mm how easy .I want to hear all oppinions only criteria is stay thrifty with ammo going from 20 cent to 50 dollar ammo not a great option when 6 of my kids 3 nephews and my wife all practice with rifle ..But 7.62 ammo accuracy........need i say more

    Frequent contributor Krochus has obtained incredible accuracy from the 7.62x39. You might look up some of his threads.

    Changing barrels is a gunsmith job at maybe $300 minimum.
    I doubt there is another cheap caliber your rifle would accept.

    You could set up to handload better quality 7.62 for less than the price of a new barrel.

    6.5 Grendel is probably the easiest switch for your gun. It's the reason I bought my 527 Carbine, but I keep getting side tracked on the project.

    Competition Shooting Sports makes a drop-in Lothar Walther barrel for the 527 Carbine (factory profile) for $325.


    If you go that route, you'd also need a gunsmith to install it for you. Or...

    Pac-nor can make you a barrel and install it on your action (as well as blueprinting the action) for you. If you go that route it'll cost you $300ish for a barrel and another $300 for the install and action work.

    (Krochus speaking) name change.

    Not all 7.62x39 ammo is created equal even amongst steel cased offerings. IME in the little CZ or any rifle wolf is probably the least accurate ammo you can buy with the exception of their 154g load which actually shoots rather well. Domestic 7.62x39 is underpowered (like everything metric we make) inaccurate overpriced garbage that's really only good for the brass.

    Far and away the best ammo I've used is anything loaded in the Russian Barnual plant. This can include several brands including monarch sold at academy.

    As others mention the ability to handload would cure all your issues

    I've had great performance out of the CZ-527 in 7.62x39 in Barnaul certainly and Tula somewhat less.

    I don't think I'd take it to a benchrest match but it will do MOA. I recently had someone tell me the cartridge supposedly the next great match round, can't say as I know.

    You said it, it is probably the ammo not the rifle. Commie factory bullets are not that precise, and US bullets in that caliber are bastard afterthoughts. I'd handload, or sell your 527 in 7.62x39 and buy one in .223. Then you can get all sorts of match ammo at reasonable prices, and you would probably do better than spending $300 rebarreling it.

    I've never seen it put so eloquently.

    One exception might be the Hornady stuff loaded with v-maxes. I haven't shot the ammo but the bullets always shot well (around 1.5 MOA)

    I think you might bite off more then you can chew trying to convert that action to most any other "normal" caliber that might shoot cheap ammo.

    The 7.62x39 is a bastard size case with a .447" case head, and so the bolt-face & magazine in the CZ 527 is made to fit it.

    Nothing based on the smaller .223 case (.378" case head) , or larger .308 (.473" case head) will fit the bolt face & extractor.

    I also agree it is not the rifle limiting accuracy potential.
    It's the crappy Russian ammo you are probably shooting.

    It would be cheaper and probably more satisfactory to buy a reloading set-up and build better ammo yourself.

    Or, sell it and buy a CZ-527 chambered in .223.

    If you go the route of selling your current 527 and getting one in .223, check to see what the twist rate of the rifling is. Last I heard all the CZ .223s except the 527 Varmint Kevlar have a twist rate geared more towards the lighter varmint bullets.

    Oh... Then PM me with a price for your 527 in 7.62x39. ;)

    You could go with 6.8 SPC.

    6.8 won't work with the 7.62x39 bolt face. You'd have to buy a 223 bolt and open it up. 223 is 0.383, 6.8 is 0.422 and 6.5 Grendel/7.62x39 is 0.452

    6.5 Grendel is a perfect conversion for the 7.62 CZ if you don't want to stick with the factory caliber. Just a simple barrel swap. I built my 6.5 with a fluted #5 bbl 22 inches long. I retrospect, i wish I'd used a lighter 18 inch bbl.

    You know the truth is that any time you have a smith swap a barrel it is going to cost you a fair amount of money.

    That 527 will sell easily and CZ makes the .223 carbine. .223 gives some of the best bang for the buck in terms of a good performing round and a reasonable cost. Bullets are available in a wide variety, brass is available at reasonable cost. Bulk ammo can be had somewhat reasonable but it is going to cost over 20 cents a round. Course if a lot of plinking and the best cost is your objective CZ also makes a pretty nice .22 that the kids and the wife would love.

    I haven't looked at the specs, but couldn't you rebarrel to 5.45x39 without worrying about modifying your bolt head?

    But the OP would then be left shooting the crappy Russian surplus ammo he is trying to avoid with the 7.62x39 he has now.

    Besides that, I don't know of any barrel maker selling a .217" caliber barrel blank.

    5.45x39 uses a much smaller diameter case

    "You can't get there from here".

    There are wonderful reasons to rebarrel an existing rifle. This isn't one of them. Seems rather silly to me to spend $500-$600 on a rebarrelling project to go from one chambering utilizing substandard ammo to another using equally substandard ammo. Not to mention actually expecting it to perform better. Isn't that the definition of insanity? Either start handloading for your existing rifle, start buying better ammo or sell yours to buy a .223 version.

    There are really only FOUR cartridges you can rebarrel to

    .220 Russian/22ppc

    6mm PPC

    Are these the only options what about other 6.5 mm i thought there were more based on the 220 russian what are the major pros and cons of all the 6.5 s i can use im more interested in a bench hunting rifle a barrel swap doesnt scare me much if its going to be a 300 + bench gun and 300- hunting gun
