The answer to the question is, no. The bullet in a .25 is a little larger in diameter than the .22. Beyond the question, as a general rule, you should never try to fire any ammo in a gun other than what the gun is designed to fire.
No. They will not fit. Trying to force a pellet of an incorrect caliber into an airgun can break it and potentially hurt the user.
No
The short answer is no. The longer answer is, you may be able to get a .25 cartridge into a .22 caliber gun, but it will likely jam and be very difficult to get out, and if it fires, it will probably damage the gun and possible the shooter. The .25 has a larger diameter than the .22.
DO NOT ATTEMPT TO DO THS!!!!!!!!!!!
No. A smaller caliber will either not fire at all, or will split the cartridge casing if it does fire.
You should never try to fire anything in any gun other than what it is designed to shoot. The .22 rounds will most likely not fit into the magazine or feed into the pistol. If they do, it can be dangerous if it actually fires. Additionally, .25 ACP is a centerfire cartridge where .22s are rimfire.
If you're talking about the difference between a .22 short or long rifle and a .25 ACP, the .22 is a rimfire cartridge and the .25 is a centerfire. Also, the .25 is .03 of an inch larger in diamter.
No.
NO! Different cartridge entirely. The 250-3000, also known as the .250 Savage has a 25 cailber bullet, the 22-250 a 22 caliber bullet. See link below.
