well rahul lets take a brief look at .22
the cal. size we talk about ie .22, .32 etc, as you know but (what the people forget is the second part) ie .22 is 5.56 in die.
the part we tend to forget is the length ie you can have a 9MM in die and 18mm , 19mm and 21mm in length the longer the length the more powder is in it, thus the power is increased.
so a .22 for a revolver (standard) is not the same as .22 or 5.56 for the Nato rifles. As the Insa ammo is the same die 5.56 but the length is longer then hand gun ammo.
hope this is clear as mud.

Re: Why IOF .22 revolver considered "insufficient fire
Rahul: Please consider: the bullet in a .22 long rifle weights 40 grains and will be traveling about 1100 feet per second out of a handgun barrel and closer to 1300 feet per second out of a rifle barrel.
For 5.56mm NATO, or what we call .223 over here, the bullet is a similar diameter, but it weighs from 55 to 70 grains. Out of a rifle barrel, it will be traveling about 3200 feet per second. If you remember that Energy = mass x velocity squared, you will note that all sorts of things happen when the velocity is doubled or tripled to the energy.
Also, the .22 bullet has barely enough energy to penetrate the body, which is lessened if it hits a bone.
On the other hand, the .223 bullet is traveling so fast that it sets up hydrostatic shock waves. In essence the bullet is going so fast that it pushes the liquids away in an explosive manner. This effect is easily seen by shooting a high velocity bullet into a plastic milk or soft drink bottle filled with water and capped tightly.
In addition to all of this mayhem, the military 5.56mm bullets are designed to be unstable. If they hit something, the bullet will tumble. The original bullet that designed to do this was the British .303. By tumbling, the bullet makes a far greater wound channel that it would by just traveling in a straight line through the body. This gives it much more chance to sever an artery or damage an organ.
There is no comparison between the .22 long rifle and high powered .22 caliber rounds for this reason.
BTW, the .22 long rifle bullet is actually about .221 in diameter, while most .22 caliber high powered rifle cartridges shoot a bullet that is .224 in diameter.
Also, the .22 long rifle uses the old style outside lubricated "heel bullet" that has been obsolete in almost every other cartridge. In the .22 long rifle, the base of the bullet that is inside the cartridge case is of a smaller diameter than the bore of the barrel and the mid section of the bullet. Other revolver rounds used to be made like this. For instance, the .38 Special actually uses a bullet of .357 diameter. In the old days, the ancestors of the .38 Special used a bullet that really was .38 in diameter and had a heel extending into the cartridge case. But lubricating the bullets outside was not as practical as having the soft lubricant in grooves that were inside the cartridge case. The .44 Magnum cartridge uses a bullet that is actually .429 in diameter for the same reason.
With the .22 long rifle, the bullet is slow enough that the outside waxy lubrication or a copper washing does a good enough job. However, for faster bullets, a better lubrication method was needed.

Re: IOF .22 revolver
Hi,
Pl. DONT BUY IOF 0.22 revolver as it does not work with any ammo. Better raise the budget and buy 32 revolver

Re: IOF .22 revolver
The Indian carts for .32 are for Rs 65 each and the imported are for Rs 250 each, but the Imported carts for .22 is Rs 40 - 60 each. I think it is advisable to buy .22 than the .32.

Re: IOF .22 revolver
I wouldn't have minded the looks if the damn thing would function like it should. Course I haven't touched one yet but I have read reams of negatives about it. The 32 atleast works.tonytennis wrote:dont go for that IOF .22 Revolver the price if 40000 but see how it looks. finishing is soo bad looks realy ugly bette you go for .32 revolver.
