airgun barrel

dear friends...an arms dealer in Hyderabad once told me that the barrel rifling of most airguns evens out in about 5000 rounds and could require replacement...how true is this?

5000 rounds = just 10 tins of 500 pellets each. Most of us have seen airguns older than us (Diana etc). It would be interesting to learn about anyone having seen a bald bore- I haven't!

In our last conversation, you had expressed concern over the life of airgun springs being about 10000 rounds. Unless the air rifle is left cocked, the spring of Diana/Gamo/HW should last a lot longer than that.

Enjoy shooting until you run out of pellets, which is more of a worry. When the barrel or spring does wear out, they can be replaced.

Rounds ? :shock:

Surely you mean pellets...

I can't say about IHP (read : Indian) barrels but any foreign brand (excepting the Chinese) should be able to put in through unlimited pellets. The lead of the pellet, basically the skirt is too thin / flexible to damage a good barrel. The Anshultz .22 rifle remains the same even after putting through more than 1.5 lac .22 rounds.... this we saw when we competed in Delhi State...

Dev San can enlighten us more...

Dont worry about all those "Rumors " the life of the barrel is much more than that. As AI rightly said that many of us have guns older than us and they are doing just fine.
As long of the gun is maintained it should serve you well for many many years.

Mid 80's i had a brand new .22 IHP, which i had super tuned to be consistant & accurate. The axle screw did wear out and had to be replaced after about 30 thousand shots. The barrel grooves were ok till about almost 80 thousand shots.
I changed the original spring & leathers after about 30 thousand shots.
The new Tass spring lasted about 20 thousand shots & eventually broke. so i put the original spring back & it lasted me another 40 thousand shots
All this in a period of 5-6 years. Shot almost 80 to 90K pellets through that IHP never felt it was inconsistent, never felt the pellets loaded loose in the barrel.

Now thats my experience

Thats a lot of experienced advice... Thanks Shamsher :)
... and of course, most armories want the customer to play the fool, and 'advice' for repairs :)

I think Shamsher has shot way more pellets than I have. I have shot about 4000 rounds thru my .22 lr and so far the barrel is cool. Ofcourse I clean it after every hundred KF's maybe even more often at times.
My Qb has about two thousand pellets thru it and nothing wrong here too. I think wear only happens on larger caliber firearms or machineguns I guess...course I have nothing to substantiate this claim with.

Regards,

Dev

I have a molbro 23 .177 ( Diana) which i brought from britain in 66 and also a benjamin franklin .22 pump up which have their rifling totally worn down and thus are rendered inacurate at longer distances.


No idea how many shots put thru each

The rest of my airguns show no wear

At times, the cause of wear of the rifling is not use but age. I have seen a few air rifles which were not in use for a few years and with time the bore gathered rust. When these rifles were brought to use again, and the bore cleaned of rust and dirt, the rust had eaten into the rifling a bit and took away some part of the metal on being cleaned.

Benjamin barrels are made of gun metal thus no rust

The reason I could manage so many shots from a single air rifle were.
We lived in a huge bunglow spread over a few acres with a lot of trees.
Had plenty of time - No TV, no videos, & no modern day entertainments.
Most of my friends had airgunning as their prime hobby, hence had a great company.
In the 1st year we were shooting 100+ pellets each day on an average.
I think very few can achieve this now.
I would also comment on the IHP quality, it has surely gone down in terms of finishing, fitting, sights, & the precision parts are not fitted with the intention that they perform well.
I feel the IHP has gone commercial & have lost the precision touch.

Exactly my opinion Shamsher. I have a roughly 7-10 years old IHP that is way ahead of today's production in terms of fit, finish and overall appearance both on the wood and metal. The shooting behavior is smoother too.

Totally agree on this.
... as is always ion the Indian Market, once the name and demand is created, every business starts to compromise on quality.. they know 'Bichare, joh be dega, woh to lega'.. and apart from this, IHP has almost no competition :)
.. I always make it a point to visit new restaurants... the service is nice, great food, affordable, new ambience, new dishes... Once their business starts to pick up, everything goes into a reverse mode, with hiked prices, scratched and cracked dishes, dirty table tops... :)
