Dear all,

I have a hard time understanding about shotgun ammunition. There are the bird shotshell, buckshot shell etc. I thought the numbers per load is standardise throughout the industry however, recently I found that even ammo with the same number will have different pellet count. Can we say 00 is always a 9 pellet??

Really appreciate if someone could educate me in this subject and explain the shotshell terminology as highlighted below. Any site to visit.

Index Guage Shell Powder Velocity Buckshot pellet
No. Length Dr.Eq. fps size count

12HN 12 3" 4 1210 00 15
12SN 12 2 3/4" 4 1290 00 12
12N 12 2 3/4" 3 3/4 1325 00 9
20N3 20 2 3/4" 2 3/4 1200 3 20

In general, what ammo does your local Law enforcement use for duty. Do they choke their barrel?? Where do they fire on an adversary, centre mass or at his kneels ???

The pellet "number" for buckshot is the pellet COUNT. 00 buck 9 pellet contains (9) 00 pellets. Some 00 loads contain 7, some 9 and some 14 pellets, depends on the load and shell length.

Most duty shotguns for LE purposes are fixed Improved Cylinder choked, at least the ones I have been around.

Last I knew LEO were trained to shoot center mass with buckshot and slugs.

It may help you visualize the replies above by going to the following web page and seeing all of the birdshot and buckshot shot sizes side by side:
