I recently bought ammo for my shot gun but I'm unsure if it is the correct size/type. On the barrel of my shotgun it says 12 gage 2 3/4" and 3" 20 inch barrel.

The ammo I bought says 12 gage 3" Magnum 00 buckshot. It hit me when I was loading, that Magnum may not fit properly in my gun and therefore may cause damage to my gun and could cause injury to me.

Can anyone clarify if this is the correct ammo from my Shotgun?
 
I would assume it fits because it's 3" and your barrel says you can use 2 3/4 or 3". If it was 3 1/2 then I wouldn't shoot it but I am thinking this is good and safe to shoot

but why does it say magnum on the shell?

The important thing is the "inches" - the only time you have to worry otherwise is if your barrel cant handle steel shot, magnum means nothing in regards to safety of you or your shotgun.
 
If the data on the shell mark magnum and it is a magnum load, You have to trust because they won't make mistake. But may I ask how does" it hit you when you was loading" ?

It is my understanding that originally, 2 3/4 was the standard. Then, to add more punch, the ammo manufacturers along with gun smiths, developed the 3" magnum. This load it appeared was popular with the waterfowlers. 3" is 3"magnum. Magnum is a word shotshell manufacturers throw around to describe more recoil. er I mean more load. Shot shells go by gauge and fired length of shell. If we were talking rifles, you would be correct that in most cases, you would have the wrong cartrage for the rifles. Not so with shotguns!

When steel came in, many people felt 3" wasnt enough. So, the gun gurus made a 3 1/2" possibly to compete a bit with the 10gauge. However, I am told the 10g is a better idea vs the 12 3 1/2". However, if you only want one shotty and max versitility, 12 3 1/2 is the way to go.

Personally, I see no need for 3 1/2 12g. I have a gun that shoots the 3 1/2s but I have never shot that load size before, even for turkey!

The short answer is YES the ammo will work very well in your firearm. I have a few 3" guns that shoot magnums quite well. My only concern would be if the firearm was really old. But then, most if not all of that era are designed for 2 3/4.
 
OK, lesson time.

There is an upper limit on the velocity you can impart to a shotgun's wad. Above the velocity limit, you crush the pellets into an oval, and rapidly increase the size of the pattern.

The option available to the ammo companies was to adjust the charge weight up, as in increase the mass of the shot charge, and maintain the same velocity.

In rifles, magnum = more velocity than standard
in shotguns, magnum = more projectile mass than standard.

If your data stamp says 3", it will take any commercially available 3" shell.
 
magnum is the stupidist worad ever used in the gun biz.
only made worse when non shooters use the woard when talking a bout a firearm.
Makes me want to hit them with a phone book!

Because when I was loading I noticed that magnum was written on the shell itself and then I saw it on the box as well.

You can never be too safe I say. I also talked to the guy who sold it to me and he said it was just marketing crap.
