hunting rifles that chamber pistil ammunition.

I don't know of any rimfire loads larger than .22 lr that are both pistol and rifle capeable. Got me stumped. I would also like an answer to this, question.

The first rimfire cartridge was the .22 BB Cap, which used no gunpowder by relying entirely on the priming compound for propulsion. Dating back to 1857, the .22 BB Cap is essentially just a percussion cap with a round ball pressed in the front, and a rim to hold it securely in the chamber. Velocities are very low, comparable to an airgun, as the round was intended for use in indoor shooting galleries. The next rimfire cartridge was the .22 Short, developed for Smith and Wesson's first revolver; it used a longer rimfire case and 4 grains (260 mg) of black powder to fire a conical bullet. This led to the .22 Long, with a longer case and 5 grains (320 mg) of black powder. The .22 Long Rifle is a .22 Long case loaded with a longer, heavier bullet intended for better performance in the long barrel of a rifle. The .22 Long Rifle is the most common cartridge in the world. While larger rimfire calibers were made, such as the .41 Rimfire Short, the .44 Henry Flat devised for the famous Henry Repeating Rifle, up to the .58 Miller, the larger calibers were quickly replaced by centerfire versions, and today the .22 caliber rimfires are all that survive of the early rimfires. The early 21st century has seen a revival in interest in rimfire cartridges, with two new rimfires introduced, both in .17 caliber (4.5 mm).

Below is a list of the most common current production rimfire ammunition:

* The powderless .22 Cap rounds, including BB Cap, CB Cap, and CB Long versions
* .22 Short, used for quiet plinking and Olympic and ISSF 25 m Rapid Fire Pistol competition until 2005
* .22 Long (obsolete)
* .22 Long Rifle (.22 LR), the most common cartridge made
* .22 Stinger (slightly longer case, same overall loaded length - the basis for the .17 HM2 [1]
* .22 Extra Long (Obsolete) [2]
* .22 Winchester Rimfire (.22 WRF) AKA .22 Remington Special (obsolete)
* .22 Winchester Magnum Rimfire (.22 WMR)
* .17 Hornady Magnum Rimfire (.17 HMR), a .17 caliber based on the .22 WMR case
* .17 Hornady Mach 2 (.17 HM2), a .17 caliber based on the .22 Stinger case [3]

A new and increasingly popular rimfire, the 17 HMR is basically a .22 WMR with a smaller formed neck which accepts a .17 bullet. The advantages of the 17 HMR over .22 WMR and other rimfires are its much flatter trajectory and its highly frangible hollow point bullets (often with plastic "ballistic tips" that improve the external ballistics performance). The key disadvantage of the .17 HMR is its cost (at present, over twice that of the .22 WMR). The even newer .22 Long Rifle based .17 Hornaday Mach 2 and offers similar performance advantages over its parent cartridge, also at a higher cost. While .17 HM2 sells for about US$6.00 per box of 50 rounds, six times the cost of inexpensive .22 Long Rifle ammunition, it is still significantly cheaper than most centerfire ammunition, and somewhat cheaper than the .17 HMR.

A notable rimfire still in production in Europe is the 9 mm Flobert, which can fire a small ball, or even a small amount of shot like a small shotgun shell. The 9 mm flobert is often called a "garden gun" in the UK, as its power and range are minimal, and it is well-suited for use in gardens, where the next-largest shotgun (a .410 bore) would be too devastating amongst the cabbages. The 9 mm Flobert is used to eradicate vermin such as mice and rats, and pigeons roosting in sheds.

There is a type of ammunition for the .22LR that fires a small amount of #12 shot (about 1/15th ounce). The shot is only marginally effective in close ranges, and is usually used for shooting rats or other small animals. At a distance of about 10 feet (3 meters) the pattern is about 8 inches (20 cm) in diameter from a standard rifle, which is about the maximum effective range. Special smoothbore shotguns, such as Marlin's Garden Gun can produce effective patterns out to 15 or 20 yards using .22 WMR shotshells, which hold 1/8 oz. of #11 shot.

Shotshells may not feed reliably in some magazine fed firearms, due to their unusual shape or relatively fragile plastic tips. Shotshells may also not produce sufficient power to cycle some semiautomatic actions.

Life is short, THIS IS NOT A DRILL!

Indiana's new law about rifle hunting doesn't say anything about centerfire cartridges. A rifle may be used that fires hand gun cartridges with a min. case length of 1.16 inches, and max. case length of1.625 inches. In magnum cartridges there's .357,.41,.44 and the .45 winchester mag. 44-40 winchester, .45 colt, .454 casull, .475 linebaugh, .480 ruger,50 A&E and the 500 S&W are all acceptable rounds in a rifle.
