what is magnum ammo
 
hi every one
i just purchased my first shotgun remington 870 tactical, i dont know anything about shotgun ammo i just started reading i learned about the sizes i purchased 3 1/2" ammo 00 buckshot then i found out that my shotgun can only shoot 2 3/4 or 3 (that what the barrel says)
now i wanna buy some ammo i wanna make sure that it is safe to shoot with my shot gun, my question is about the 3" 000 magnum buckshot is it safe to shoot this ammo with my shotgun ? and why they call it magnum what does magnum means and what the deference between amo same length and size but one says magnum?

Magnum refers to the pressure that a particular cartridge is loaded to in relation to it parent or progenitor cartridge. For example a .357 Magnum is derived from the .38 Special, likewise the .44 Magnum of Dirty Harry fame is derived from the .44 Special. In the case of shotgun shell the 3 1/2 and 3" shells are referred to as Magnum in relation to the standard 2 3/4" loads. If your barrel is marked 2 3/4 and 3" both can be safely fired...the 3 1/2" cannot. Be forewarned, the 3" 000 buck will knock you on your ass if you are not expecting the power that it delivers...pull it up tight to your shoulder and don't let it slam back on you. Bruising is pretty much non-negotiable. :)

thank you that helped me... and what does it mean when the write low recoil i mean when they say that does it mean it has less power than the same size and length tha doesnt say less recoil?

yes...recoil is the opposite force of the round firing, to reduce recoil without changing the gun requires less power in the round.

Magnum in a shotgun is different than Magnum in a handgun or rifle. In a handgun or rifle Magnum equates to higher velocity and pressure. In a shotgun Magnum generally means heavier payload at comparable velocity/pressure. A standard 2 3/4" 12 ga shotshell will have a payload (weight of shot) of 1-1 1/2 oz. A 3" shotshell (pretty much all called Magnums) will have a payload of up to 1 7/8 oz.

It's amazing how much more manufacturers get into 1/4". A 2 3/4" 00 buckshot has 9 pellets. A 3" 00 buckshot has 15 pellets. With slugs you have a choice. Some brands like Winchester Super X have the same payload with another 1/4" of powder. Other brands put larger slugs in 3" hulls.

I would spend a little time at a site that advanced filtering so you can compare loads. Sometimes the 3" gives you more bang for the buck. Other brands don't give you anything that makes the round more effective.

FWIW, thre have been different terms to indicate higher power/performance over the years. At the end of the black powder era, the term Express was used- as in Express Train (high speed transit). Magnum is a term used to denote a bottle of wine that is larger than a standard bottle- and was used to denote the higher energy cartridges. At times, Super (.38 Super) were also used to designate the "new and improved" cartridges.

To the OP- read what is on the barrel of your shotgun, and stick to that ammo. Just because it fits into the gun does NOT mean safe to shoot. A 3 inch mag will fit into a shotgun meant for 2 3/4, but is not safe to shoot.

And, IMHO 3" ammo has a purpose. Waterfowl hunting and dangerous game. Two legged vermin are not that tough. All you get from 3" buckshot is a thinner wallet, more recoil and slower followup shots.

and one more question is the recoil from 3" 000 more than 3" 00 or slug?
