IOF .22 LR rifle

[TwoRivers]

i recently got a used .22 gun and got the stock maodified by my own carpentar and gun blued by local gun smith but wen i test fired it to my horror the fired rounds are not ejected. What could be the reason , may be the acid treatment and chenical dipping may have tightened the seat of the rifle cartride. , or a loose spring ,

my freinds please guide what to do...

regards

With a .22 RF failure to extract is usually caused by excessive dry firing, and a firing pin that strikes the chamber rim. This will raise a burr that catches the fired case, and the extractor will slip off the rim. Second, could be a weak or broken extractor spring, or broken extractor. Take the bolt out, put a cartridge into the bolt face under the extractor, and pull the cartridge straight forward. If it readily pulls out, it's the extractor/spring. If not, and only after firing, it's a chamber burr. Any gunsmith worthy of the name can fix that for you by ironing out that burr. Good luck.

well i was very disappointed with performance ( or bullshit ) of my gun when it stuck the cartridge on very fist attempt.. luckily i found a good gun smith in our own city and he rectified the problem by making the chamber seat of the rifle smooth by his jugaad and aligned the magzine and i just brought it back from him test fired it three times and to mi surprise , the rifle is just same as i used to shoot "videshi " guns like brno etc.

He told me that iof products are under-machined so we have option to get then reworked .A tight seating og fun can be loosened but problem arises when there is loose seating.

the real problem was that the previous owner did not used or tried to use the gun extensively , just kept it for having a gun. So dd not bothered to get it ok. the grooves are in a brand new position and am advised to put a drop of oil before firing as to prevent occasional jamming. After say 100 fires it will be better.

i will go to range on sunday and try the results and grouping will decide what is outcome.

but as far as the gun is there it is working and lethal and that is also important factor.

The fellow who told you this needs to have his head examined.Shoot with a dry bore and chamber.Oiled cartridges are used to proof test firearms.

When you fire a firearm,the cartridge case expands momentarily,gripping the chamber walls.If you shoot with oil in the chamber,the case is not able to grip the chamber walls.It leads to increased bolt thrust.Bolt thrust is basically the rearward pressure on the bolt.

I am sure more knowledgeable members will correct me if I am wrong.

Also,if the chamber is undersized ,you need a .22 reamer to bring it to the correct specs.

Only the British proof method used an oiled case/chamber and actually measurering the rearward (bolt) thrust; then calculating the pressure. Continental Europe and the US used a copper crusher located at the side of the case, no oil. European and US methods differed in that the Europeans pre-drilled the case, getting slightly lower, but more consistent, readings. Today Piezo transducers are used instead of copper crushers, again the placement methods differ, giving slightly different readings.

A shot fired from an oiled bore will go wide of the group fired from a dry bore. The bore should always be wiped dry before shooting, and the first shot not fired for group.

Reminds me of the story of the war between Lilliput and Blefuscu Thanks for the information.

well after much hype and turmoil i now carry a .22 lr which shoots good with "videshi " lapua or Winchester ammo , but on kf tis totally a fail , since when i fire lapua and Winchester there is visible hit mark on the cartridge but on kf there is not at all any mark of hit , am still unable to understand , the size of both videshi and desi cartridge seems same to me , however i have not measire the thickness of the rim. or may be the firing pin is little smaller that does not make up for a hit on rim. still mi voes not seems to end .. please advice me seniors waht to check and do ....

A gun smith, Sabirbhai at Dehradoon, has a reputation of modifying iof .22 rifles into brno with change of stock and tapering of the barrel with bluing. He claims iof is as accurate as brno! If interested contact him at 9897336996. His stocks are simply immaculate with chequering to match the best.

Dear Andy,
I believe the gunsmith being referred to is Sabirbhai. His shop cum residence is adjoining the old city bus stand, his shop name is perhaps Dehra Arms, and his mobile is 9897336996.

Hi,
I have seen .22 IOF. Said to be modified in Trichy. Much smaller , shorter,lighter and tapering barrel.
Don't know about the accuracy.

Not sure if its the OFB Trichy or some private armorer in Trichy.
I think this reason should suffice for not calling the factory.
If some information are tuck away up in your sleeve regarding this matter please donot hasitate to share with us.

Hi, I am getting a brand new .22 IOF rifle. The price is 58K. Is the price reasonable ?

And for your information, I had a chat with a RFI officer today who told me that the booking is now open for .22 rifle but the waiting period is 10-12 months.
