What kind of shells go in a 20 guage shotgun?
84772
20 ga. shells. The shot can be from double ott buck shot to number 9 bird shot.

#7 birdshot.  Minimal drywall penetration and good stopping power.  Only reason to move to 00 buckshot is if you are defending over a longer distance or in winter when bad folks might wear very heavy clothing.

Hornady SST's.  They're unbelievably accurate with the ballistic tip out front.  \nI've done really well with Brenneke's too out of my rifled slug barrel, but nowhere near as good as the SST's.

the first answer from chris was correct. given youre choices of a short barrel length i imigine you are going for a rifle in the 22 lr to 223 remington caliber. get what ever you want because the burn rate of powder from those calibers will be sufficient in a 18 inch barrel and a 20 inch will add none or very little velocity. i notice you are talking about just heavy barrels. if it is just a bench rest rifle and wont be used for carrying i would opt for the longer barrel. but to get to ballistics i have 2 ar-15s both from dpms. one is a 16 inch heavy barrel and the other a 20 inch heavy barrel and they are identical in accuracy, actually i keep tighter groups with the 16 inch but it is a flat top and has alot better scope than the military versions that mount through the carry handle.

a case(1000 rounds) for each caliber you have, if you have a few of the same caliber it's recommended to have at least a case for every 3 firearms of the same caliber.If you're an avid shooter you might want to get into reloading, save all your brass, look at dillon and lee progressive presses, or a rockchucker single stage. Make sure your dies are carbide as they last the longest.

As several have already advised, you want to use small shot and relatively low powered loads.  Extensive testing has been done with all variations of shot and shell that you can imagine for both law enforcement and civilian use.  I have reviewed and participated in many trials using typical housing materials and human ballistic compatible materials to simulate the effects of many different weapons, including shotguns, in a home environment.   Even with low brass, target or inexpensive field loads (#7 - #8 shot), the terminal effects were devastating within 2-15 yards.\n\nIn this range the shot pattern has very little chance to open up more than a few inches and thus most of the pellets and energy of the round is concentrated in a very small area of the target.  Total penetration of the pellets depended slightly on clothing, but typically ranged from several inches to more than 8".  In many of the trials the ballistic simulant was either cut in peices or turned into mush.  The small, soft lead shot also had a lessened tendency to penetrated both sides of a typically constructed home interior wall after passing through the target.  Most of the energy that remained after exiting the target was dissipated when the pellets hit the building materials and deformed due to their soft consistencies.\n\nSteel shot and even larger soft lead shot, proved to be much more apt to over penetrate or ricochet than small, soft lead pellets and I would not recommend steel, hardened or large diameter shot for home defense.  It is important to note that even small,soft lead  shot can't be called safe when discharged inside a building due to many known and unknown factors.  Known factors include, but aren't limited to pellets that miss the target and strike walls or ceilings without first passing though the intended target, weakened or varied building materials that the pellets may strike, distances and number of walls between bystanders and simply the innumerable dangers posed by discharging a weapon in such close proximity to others in an uncontrolled situation.  \n\nWith that said, if choosing to use a shotgun for home defense, I would stick with small shot and low powered loads.  There are even several rounds available in less than 2 3/4” sizes for all gauges of shotguns that provide ample terminal effects, but help reduce collateral damage even further.  Please remember that no matter what weapon you choose or what ammunition you pick, any can and will be lethal to humans under the right circumstances and should always be treated as such.  The opinions I have expressed here are simply to demonstrate how you might choose a relatively "safer", but effective loading than others mentioned in other answers to your question.  \n\nAgain I emphasize that that there is no load that is truly safe and could be relied upon to not seriously harm or kill another person either intentionally or unintentionally.  Even low powered loads and small soft lead pellets, can travel though walls, windows or any other housing material and still kill a person on the other side. Make sure you get some training and advise of a Certified Firearms instructor not only  to increase your safety and proficiency with your weapon of choice, but to help you with the weighty legal aspects of this topic as well.

Bound's hubby here: \n\nExpect that your Springfield double is chambered for 2.75" 12 guage shells. Twelve guage shells were also once offered in 2 9/16" length, but the chances your shotgun is chambered for these shells is really slim ... about equal to you having Osama Bin Laden at your dining room table for Thanksgiving dinner!\n\nEDITED TO ADD! Do NOT drop a 3" shell into a 2 3/4" chamber, this will give you a false indication! Shotgun chambers are cut long, because the folded "crimp" opens up into the chamber extension. If this did not happen, the shot and wad would be constricted as it passes into the barrel, increasing chamber pressure to the point that you are risking a blow-up of your barrel! If you use the "drop test" and see that a 3" shell falls into the chamber, and you use a 3" Magnum (the only 3" shell), you are not only risking destruction of your shotgun, but also risking bodily harm!\n\nGood luck!

It's a Marlin 336 relabeled and sold with the J.C. Higgins name.\n It's a 30-30 caliber.

Your best bet for trapshooting is usually going to be a 12ga. 2-3/4" shell w/ 1-1/8oz of number 7-1/2 or 8 shot.  This load with a improved choke tube will usually do just fine out to about thirty yards or so, depending upon your level of skill and level of comfort with the particular gun.  If you are going to be shooting longer distances, you may choose to use an modified choke tube, or go to a size 6 shot which should so just fine to forty plus yards.  You will have to play around with ammunition from various different manufactorers to determine, if your gun shoots better with a specific brand, or if you just like a brand in general.  Personally, I would reccommend looking at Winchester AA target loads, or Kent all purpose loads.  I have had the best luck with either of these two, but I will usually shoot anything that is of good quality and realatively cheap.  Once you have figured all of this out, have fun and be safe.

There are basically 2 types of cartridges rim fire and center fire. The most common rim fire cartridge is the 22 caliber and if you look at a spent casing you will see the strike mark from the hammer is on the edge-rim.\nCenter fire cartridges have the detonator in the center . The caliber refers to the size of the projectile that is in the end. The casing is the brass part that is left in the gun. Casings are different depending if they are for a rifle, a shotgun, a revolver, or a semiautomatic handgun.\nA revolver is the kind of gun with bullets placed in a cylinder- like on westerns. A semiautomatic uses a clip to hold the bullets.

CCI, Remington and several other brands offer shot shells in 22lr. Some are crimped metal casings and others have a blue plastic cap that holds the shot. I believe it's #9 shot.\n\nWinchester, Anschutz and several other firearms manufacturers offer smooth bore rifle chambered for 22lr shot. I've even heard of rural gunsmiths that take old beater single shot 22, bore out the barrel and offer them for rats, pigeons, and other nuisance critters.\n\nA search on http://www.gunsamerica.com will yield some for sale.

spend the money and buy a Benelli Super Black Eagle II it will give you a lot of versitility i.e. 2 3/4",3" or 3 1/2" shells and it will give you years of reliable service without a ton of time cleaning it. i have several Winchester pump guns and i leave them all at home in favor of my Benelli. (no comparison), you get what you pay for.

A choke tube changes the restriction at the end of the barrel to change the shot pattern. You would use a looser (imp. cylinder) for close range shooting and a tight (full) for long range shots. \n The site http://www.maverickarms.com/pages/choketubes.htm will show you the different choke tubes made for your gun.\nIf your gun has a fixed choke tube it should be stamped on the barrel. Most were Full or Mod(ified). If you want a barrel with interchangeable choke tubes you could pick up another barrel for your gun. They do make an accu-choke (brand name of the choke tube) barrel for your gun. Any Mossberg model 500 barrel, in your gauge, will also fit your Model 88. You should be able to find them fairly cheap.\n eBay usually has 15-20 Mossberg barrels listed in 12 gauge. One just sold for $60.00 with one modified choke tube. Additional choke tubes are around $10-20 on eBay or $20 and up at a sporting goods store or gun shop.

berretta is a superb shotgun, but if your wanting the same durability and save some money go for a remington. i have a 67' model remington 1100 12 guage, that is all original rite down to the rubber o-rings around the gas piston. never had a problem out of it, all i have had to do was keep it clean. still shoots as fast as a new one, and 100% dependable.

You really can't reduce the shot pattern in a .22 without modifying the weapon. The best answer i can give you is simply to shorten your shooting range. If you want a tighter group with a .22 shotshell, shoot closer. Your only other option is to try a few different ammunition manufacturers to see which round groups best from your particular gun. I know i get excellent results from CCI .22mag shotshells in my Heritage Arms Rough Rider, while most other ammo gives a much wider spread.
