shot out?

cbrjohnthou

Is it possible for a gun to become 'shot out'. A friend of mine has a brno.22 for almost 12 years now and has tried to zero it with 2 dif sets of scopes. the bullets are going everywhere. Is it possible that so many rounds has gone through this gun that its( for the want of a beter word) SHOT OUT. Both scopes and mounts are perfect.

possibly not shot out shank ,it might not have been cleaned for 12 years or the barrel was wet when it was put away and has pitted or rusted

Take off bolt and look through barrel to see if there is pitting etc

Give the barrel/action a deep cleaning.

Check that the barrel is fully floated.

Check the mounts and rings are correct/suit.

Strip the bolt and clean thoroughly.

Try as many different bullets as possible. (Bruno's usually like Lapua, so try either super club or Centre-X. Just for grouping).

If none of these things work get to a gunsmith (Fergal White) and ask him to stick a bore scope up it and check things neither you nor i would think of.

A round with a piece of grit in it can play havoc on a barrel.
Rust can have the same effect
Hoppes benchrest will take out any gunk if there.

,22lr normally are good for 20000 rounds due to low velocity, however if the barrel had dirt in it when fired their could be a pitt in it,

I would:

(a) inspect the bore and clean thoroughly
(b) take the scope off for now (if the rifle has iron sights)
(c) try as many different brands and types of ammo, from sub sonic, std velocity, high velocity and hyper velocity.

I have a Brno .22 that is from 1969, and it still shoots fine. It loves Eley subsonics and CCI subsonics.
However, at the range recently I tried some old hi vel stuff I had lying around. 6" groups at 50 yards - atrocious!! Switched back to my subsonics, and everything reutrned to normal.

Unless the bore is damaged it is hard to see a .22 wearing out. The bullets are usually soft and going relatively slow.

I would double check the scope mounts too. An improperly mounted sope could cause the problems you mention.

It wasn't me!

A .22 isn't going to get shot out within twelve years anyway, and certainly not with normal use. We've got some Anschutz rifles with the guts of forty years under them in the club and they still shoot far, far better than anyone currently using them. You won't see pitting with the naked eye or the effects of a shot out barrel, so might be worth getting a decent gunsmith to look at it first.

well to be honest he hasn,t washed himself in about 12 years either so I'd doubt he worried about his gun, I know us bikers are somewhat scruffy but he takes the biscuit.:D:D:D:D.

I'll tell him to put some Hoppes through it and see how it goes, but he reckons it always fired perfect up until about a year ago.

Is the Rifle a .22lr or a .22SLLR?

Try looking down barrel with bolt removed

Ah, good man TB. Better than spellcheck.

Normally the barrels is the last part to go. It could be the bolt face not flush letting out gas.

However I have seen a lot of rifles that rounds with grit were put into and seen the scoring/pitting.

My Da's rifle is a 1964 Anschutz SLLR and it prefers low velocity ammo.
Twist rates may be different etc.

I have not time to check just on a study break at the mo

What light source did you use to light up the barrell that well Tack?

Day light if you are in darkness, or i have a little GERBER LED torch that does the trick. LED works well as it is brighter.

If you try and look at the barrel at an angle. You can use a mirror also to refract the light and a mirror and magnifying glass led combo either.

Roughness or pits cast shadows and change the light beam.
i hope I am explaining myself well, its trial and error with angles etc to get best view

patsat

i usually just take the bolt out and look down the barrel at a lightbulb, may try it wit an Led my brother has a .22 lever action that we cant get to group atal!

Far from JW, I'm decended from engineers who all loved firearms

If I knew half what my granddad did I'd be doing well.
Plus I have been into Rifles all my life, if you knew how much time I spend on them you would put me on a par with a geek!

And I am an engineer by profession might have something to do with it too
And I have a great memory

I can not play football (useless) nor am I any good at cryptic stuff.
I'm just into guns and ammo
Why do you think I was christened tackleberry??:D

Well I am currently studying outside the box thinking in engineering.

I'm not German, born and bred on these sweet shores, but I can see you are sniffin JW to see who I am, it's no big secret but i do not discuss mine or anybodies nom de plume online

I just love guns,motorbikes, engines, and military stuff.

i have not a clue on soccer gaa golf or any of that craic, nor want to know.
If something interests me I always ask questions, in college I used to wreck some of the lecturers heads as I'd ask questions on accuracy, metallurgy and thermodynamics but i was only interested from a shooting or motorbike perspective.

I have to make sense of things in my head, just the way I am.
I love learning, still studying. Everyday is a school day; Most brilliant mind i know thought me that!;)

might be worth checking the rifle barrel's crown, if its damaged it would cause wide, irregular groups. The smalest things often cause the biggest problems;).

Re-crown could be the way forward.
Dial it in on a lathe and check the two angles to see if they are concentric
