    Brno Fox query

    Hi everyone, I have an old Brno Fox in 222, shoots ok but the barrel sadly has a fair amount of old pitting, so itís not going to get any better, and Iím keen to renovate. Iím aware that the CZ 527 is a newer version, can the CZ barrel be screwed into the Fox receiver? Iím guessing the action will be longer on the 527 as itís a 223, but are they compatible any other ways? Thank you!

    The moral of the story being that anything can be attached to anything, given enough time and money.

    What's "shoots OK" and how good do you want it to shoot?

    Brno Fox and CZ 527 both have 25 x 1.25 threads
    The magazine lengths and action cutout are different between 222 and 223 actions AFAIK

    ‘Shoots ok is just under 1” in field conditions, which is pretty good I guess. The blueing is quite badly worn in places, it has been shortened and has no open sights. The CZ barrel would be 1 in 9 twist which might be too tight for 222? Ok for 55gr perhaps?

    Yip same barrel but the fox .222 mag is shorter than a .223 mag. Easy to trim a 527 .223 barrel up a bit and ream it to .222 though. The new 527 barrels are all 1-9" twists but they still shoot the lighter stuff well, 40gr to 70gr.

    My CZ 223 has a 1:9 barrel and it shoots stunning groups with down to 40 gr V-Max projectiles which were actually bought for my Hornet.
    Have some 35 V-Max projectiles for the Hornet as well which I might try in the 223 one day, for giggles.

    It also shoots great groups with 53gr and 55gr projectiles but couldn't get it to group with heavier stuff like 69gr which the 1:9 should stabilise.

    The 69gr projectiles were a long discontinued Berger. The Berger calculator said they should be stable. I just stuck to around 55gr in the end.

    Should try them. No doubt unobtainable right now.
    What powder? @Wingman
    I've always sworn by BM2.

    Thanks for that. I've got 2206 and 2206H.

    Robert is out of stock. Amanda to the rescue, order placed.
    Thanks for your help.

    Thanks Wingman and Zimmer, really useful advice. Iíd probably look to follow Wingmanís suggestion and re chamber to 222, I kind of like the idea of 222 as a caliber, and Iíve spent too long shooting 5.56x45mm for a living to own one for fun! I like the idea of a light, accurate rifle in caliber that when shot properly will deal to deer, goats, small game etc, whilst also being ideal for my kids to learn to shoot with one day.

    Any idea what a gunsmith would likely charge to do the above? In the past Iíve used Alan Carr in Paraparaumu, he is fantastic at sympathetically working on or refurbishing old rifles.
