Bought a legendary Brno #1

[barrabruce]

Well a bought a barrelled action without a stock.
And only one bulge in the barrel.
Well it turned out to be 4 bulges but who’s counting.
Fitted it in what looks like a Chinese slug gun stock.
Shot it then lopped off the last 3" of barrel to get back past a bulge and to good rifling.

Phew.
The firing pin channel in the bolt seems like it was machined with a hammer drill and wood spade drill.
It is wobbly and to adjust the trigger right low it makes it unsafe if you breath the wrong way.
Are they all like this?
Any great fixes?
The trigger pull is nice enough adjusted back some but I’m thinking of more the consistency of ignition for accuracy.
It seems to bottom out and sent vibrations though the stock into my ear and seems loud but it isn’t when you take your head off the stock, if that makes sense.
Is it me or am I expecting too much.

Thanks
Bruce

After trying to shoot off bags and getting no where I just shot using the bags as support for my leading hand.

10 shot group of cci std at 50 yards which is about a 5cent piece.
See Attachment 280307
May get a bit more out of it but probably good enough for rabbit shooting.

Thanks for visiting

Interesting. The group seems to be circular. If that's the case then maybe hang a weight on or near the muzzle or check the bedding. On the other hand, for a fifty yard group, that's not too shabby.

What ammo do you have available in your parts? I've been trying a bunch of different ammo and been getting interesting results. Some ammo shoots better in different rifles. Some pretty good and some not so much but change rifles and it's the other way round.

You know, a rabbit is somewhat bigger than that coin and I challenge you to hit that coin offhand. With that group, you would have hit it with every shot! I'm betting a rabbit would stand no chance with you behind that gun out further than 75 yds. And CCI Standard doesn't shoot better than that anyway.

[barrabruce]

Interesting.

Well CCI does better in my ‘ol Remington lopped off shorty usually.
This is on the same target with a cold clean barrel.
It does better but I just sent them down really.

That’s when I changed to shooting holding the gun like I always have.
These groups are with the rest and I shot them after other ammo without any foulers or lubers whatever.
I’ll have to wait till I can make a day of driving to get more sample ammo.

I used cci blaser 10 shots which was an eye opener.
Eley sport green packet cheap? Stuff.15x
Federal champion std velocity with tarnished cases.10x
Cci std my go to.
I’m keeping my old stock of cci std for real work as the post apocalyptic and covid stuff I get more erratic odd ones.

Interesting all the cheap blamo ammo has gone up and a lot are now/ was @$10 a packet which is expensive but the likes of the cheaper level target ammo are looking more appealing.

I may take my 10 ths mic with me and measure some ammo to try if I can.

This could take a while before I make the journey up the big hill again.

[Mk42gunner]

Groups don't look bad to me for a gun in the condition you describe.

Never knowingly held a real Brno #1, I can't say as to the normal quality; but I thought they evolved into what is marketed in the US as the CZ Model 452. I could be wrong about that, but the bolt root sure looks familiar to me.

Robert

[barrabruce]

Well you are correct.
The first brnos were made of sterner stuff.
Ordnance steel like may of that post war era.
The barrels are hard stuff and screwed into the action.
The trigger in mine is different and the safety lever but hasn’t changed that much.
The ones had a tight choked bore and are supported to be better than the 2’s
I don’t really know if it is nit picking or not.
My hadn’t been used much but is slippery smooth.
You can hold the muzzle down and it will chamber a round after I fixed the mag feeding and if you lift the bolt it will slide down with the empty case if you raise the muzzle.
The barrel looks the same as my 1958 hornet so I could graft it in more or less if I have to.
I will put up some pics if you are interested.
They have a following over here and they made a model 2 I believe for the Ozzie farmers a gun to have.
Better than that new stuff. Ha.

[barrabruce]

The photos that I think are different and may or maybe not relevant differences.
From what I have seen at the range and read roughly.
Big point. barrel is 20mmx1.5 Pitch threaded and the action is 30mm diameter.
Barrel is beefier and did have a mid barrel screw and pressure from the fore-end tip.
Attachment 280322
The trigger is a adjustable 2 stage on this one and adjusted to single let off by me.

To the bolt
Attachment 280324
I believe the locking lug is bigger.
The handle has a ball indent to lock into the action when closed.
The safety is in inline with the bolt.
You have to push forward on the trigger to realise the bolt from the action.
Attachment 280325
The firing pin sear is tapered back wards and doesn’t ride the trigger on release.
The firing pin is a rectangular wedge shape that protrudes nearly but not quite to the bolt face.
Attachment 280323

As you can see a rough in letting and a make do bedding job with JB weld as it was all I had.
Attachment 280326
I may take off the side bedding but will leave it for now.

The barrel has had a light Lapp but I will leave it unless it is needed.

I may try hacking the stock up because it is slightly cactus wompus to favour those right handed lunatics.
And see how’s she goes.
Next time I’m digging out my dodgy wind flags.
Splattering a bit of chicken blood around.
And hell why not ..... even have my yearly bath ....if I need it or not.
Ha.
Standards must be met.

[tazman]

Don't forget to experiment with a potato in your pocket!
Much depends on which pocket and how large the potato. Also makes a difference if it has been freshly washed or has eyes starting to grow out.

[Mk42gunner]

Thanks for the pictures.

Also, please remember the potato goes in the front.

[barrabruce]

Well I’m ready for the week-end.
It may be raining and blowing.
If I can get it abit better I’ll take it.
If not I’m pulling out all stops and following O.S br thread I’ve been inspired to try those tuners again.
I bet everyone’s eyes will boggle with jealousy when Clap their peepers on this one.
Attachment 280582
Ha
I got a few empty different Eley coloured packets to put my cci stds in.

[barrabruce]

Well that tuner lasted the time sitting in the safe and taking it out to play.
I must have picked up a burr or something and the soft aluminium gualled and froze.
I shoulda put some never seize on it. Dohhh!

Made this instead and I think it looks better and I won’t have to put up with.
"He’s got a silencer on his gun” and all that nonsense.
Honest you don’t know how much trouble people will cause you just because they get something in their minds.
Then they get offended because they were wrong.

Jeepers creepers that looks like something from the adult toy store, and I don't mean a gunshop

[Jniedbalski]

I got burno. #2. What difference does it have with the #1? I really like my burno. I have a China jw15 which is a copy of the burno. This is a military trainer not a import gun so it’s very well made. It’s so muck better than the ones they built for import. It shoots as good as the burno with match ammo. I remember buying it out of shotgun news for 200$ back in the spring of 89. I thaugh I was getting a real burno. After I got it in I was highly upset it was a Chinese made and not the burno until I shot it. It would hang with the burno a
On accuracy. And the jw15 had a really good adj trigger where the #1 didint I thank. The trigger is amazingly on the jw15. I

[iomskp]

Had I known you were looking for a Brno No 1 you could of bought mine with stock.

[Stephen Cohen]

my uncle was from up your way barra, and when he died a couple years back his wife handed his Mod 1 into Police before he was even buried, it originally was my Gran dads and the Cop begged her to sell it rather than have it destroyed but she had it destroyed, it was in mint condition and I was a few days too late to get it. My brother and I wanted that rifle and never knew what happened to it after old Pop passed. You may cry now. Regards Stephen

[Mk42gunner]

Well Browning called their barrel tuner the Boss, what are you going to call yours? Bathroom attendant sounds reasonable.

Robert

[barrabruce]

I don’t know what to call the tuner yet.
Thinking buttmaster 2000 with optional pile scratcher.

Tried some more ammo today.
It doesn’t mind cci std and cci blaser but seams to have expensive tastes with Eley cameo ammo.
Hated Sk and Winchester.
After the Winchester it was spraying bullets till I got the/some lead out of the bore.
So I think are too small but I will measure them to see tomorrow.

Cci std best group and some more.
Attachment 280787
I found The rifle was jumping off the bags and the projectile was hitting pretty well where it went.

I ended the day trying to shoot the staples out of the target snuggled up in my small shooting bean bag and towel as a rest.
Got close on a few .Even clipped one twice
Think I got to either learn to use a rest .Do something to the stock.
Attachment 280788Attachment 280789Attachment 280791
Given up for now.
Tried the tuner but the hole may have been too small and the blow by was harassing things.
I shortened it and increased the diameter so it may work next time.

Still mostly the 5 cent piece range with ammo it likes.
Greased the firing pin and hole where it sits and seems quieter.
Tried some cardboard from the ammo packet in the for-end tip but did nothing.

May try some silicone in the stock.

Don’t know what everyone’s does but it maybe the limit for this one.

Thanks for watching
Bruce

[Mk42gunner]

Don't know if this will help your groups or not; but I have seen people get their rifle settled in the bags with their shoulder not even touching the butt of the gun and squeeze the trigger by pinching the trigger and trigger guard. Free recoil isn't going to cause a .22 to move much, and in theory it may help.

Personally, I always want to hold the rifle with at least my firing hand.

Seeing your five cent piece made me think of how long its been since I visited Australia. Hard to believe it was twenty five years ago.

Robert

[barrabruce]

I measured the ammo today.
From the box I tested just plucking rounds.
The cci std old school batch 0.224" 80%plus some 223"
New cci Std 0.223-4" mostly 0.2235"

Blaszers 0.2243" avg
Eley edge 0.224" pretty consistent with that weird crimp and blk case but the lube seems white spotty (heat maybe).
They seem the best in this rifle so far.
Cci std new stuff a bit flighty at times but below eley.

SK std plus 0.223-4" from measuring should shoot but it might be the slippery lube or they speak a foreign language who knows they must be leaking in the bore to have such consistency but shoot so bad.
Winchester subsonic 40 grn hp 0.223" and some minus that. Not much lube.these leaded to bore.
Maybe after it filled up the loose spots it would sort itself out but I doubt it.
Looks like this Brno1 likes the fatter bullets.
Maybe I’ll do a chamber cast and make a bump die for it.
Ha Dreaming right !!!

I will have to work on my bench technique.
Maybe I need to get the axe out and hack off the toe of the stock so it sits inline with the bore with a bag.
See if I should maybe cut the butt plate vertical..
Dunno I may have to find a stock hacking for dummies book to read.

I should make it for off hand shooting as it’s my weakest position.
Well it’s becoming more of my only position as I’m getting more remastered by time and gravity.
Ha.
5cent piece is 0.760" or 3/4" inch for us trying to get all the advantages we can.
10cent is bout an 1"

I don’t know what dime size groups are but it must be impressive too.

[Mk42gunner]

Our dime (ten cents) is approximately 11/16". Measured with a carpenter's steel tape measure, I'll try a caliper when I get home tonight.

It is also very close in diameter to your old two dollar gold colored coin, but about half the thickness.
