What are these?

Sabot
Glazer
Frangible

I see them, read about them, no clue what they are except for ammo types.

Sabot literally means a wooden shoe. It is a collar-type thingy you put on a bullet so it can be fired from a larger-caliber barrel. For instance, you could put a sabot on a .223 caliber bullet, load the bullet and sabot in .308 brass, and fire it from a .308 barrel. A sabot lets you launch smaller bullets than a given firearm was designed to fire at insane-o speeds.

Glaser is a brand name for a type of frangible ammunition. Frangible projectiles are designed to break into lots of little pieces on impact.

Others here are certainly more knowledgable, but I found a Sabot definition w/ an internet search:

http://www.geocities.com/CapitolHill/Lobby/1221/sabots.htm

sabot: (sa - bot) \ say-bow: a thrust-transmitting carrier that positions a missile in a gun barrel or launching tube and that prevents the escape of gas ahead of the missile.

So ... what are they? They are nylon 'sub-caliber bullet holders'. The sabots that are generally available allow one to fire a .44 caliber bullet in a 50 caliber rifle (44/50 : used in muzzle loaders), or a .224 caliber bullet in a .30 caliber gun (22/30). They are cupped, with small 'fingers' that hold the sub-caliber bullet in place, and also act as a 'parachute' to create drag, which pulls the sabot off the bullet soon after it leaves the muzzle of the rifle.

A Frangible bullet is one that is designed to break apart upon impact -- so they either create a shotgun-like hole in the bad guy or break apart upon hitting a wall if you miss. There's been a lot of discussion on frangible bullets when people talk about arming airline pilots -- presumably based on the mostly-inaccurate Hollywood scenario where a bullet hole in a pressurized airline cabin causes the passengers to be "sucked out" the hole.

I think Glaser is a type of frangible bullet.

Sean -- You beat me in the internet search to the same definition! You must also use Google!

FWIW -- The book "Point of Impact" by Stephen Hunter has a very interesting use of a Sabot bullet.

OK, I'll play...

A "sabot" round is one that has a smaller diameter bullet wrapped in a plastic sleeve to fit the actual bore size. Examples...the .30-30 "accellerator" rounds Have an approximately .22 centerfire (.222-.223-.224) size bullet wrapped in a "plastic" sleeve of .30 caliber to "grip" the rifling of the .30 barrel. Some muzzle-loader bullets are also 'saboted', and some shotgun slugs are, too. Sabot shotty slugs [generally] work best in rifled barrels

Glaser is a brand name for some defensive hangun ammo. Visit www.corbon.com for more info (Corbon now owns Glaser Safety Slug)

Frangible ammo means that it breaks up (fragments) easily when it strikes the target.

Perhaps not the best definitions, but I think that covers the gist of each. More knowledgeable folks than me will drop by to chat about these shortly.

Just to add my $0.02 ...

It seems to me that the old cloth patches used with a slightly undersize round ball in muzzleloaders would also qualify as a "sabot" even though they are never called that.

The patches:
1) Form a gas seal around the ball
2) Allow an undersize projectile to be fired ( about .490 in 50 caliber )
3) "Parachute" off the bullet shortly after leaving the muzzle

The Accelerator rounds used a metal sabot to propel a .223 bullet to over 4000fps out of a .30-06 rifle.

Sabot is a pretty generic term. It needn't be plastic. For example, the M1 Abrams tank main gun uses a sabot round. The sabot (two piece), in that case, weighs quite a bit more than the actual projectile.

Muzzleloading sabots are very common and are generally some sort of polymer (plastic), smokeless powder rifle sabots are more often some sort of metal and are pretty uncommon these days.

Called the Glasier Safety Slug, invented in the mid to late 70's as I recall, for theoretical use by the Sky Marshal's of the time.
Basically,it is a hollow jacket, filled with bird shot(number 7 or maybe nine...been awhile), a suspension medium and topped off with a blue plastic cap.
It flew like a bullet. On impact the shot moved forward, through the blue cap..creating a devestating, though sometimes very shallow wound channel. But, by the same token, if it hit a wall..it broke apart and was therefore theoretically 'safe'.
It was incredibly expensive, like a dollar a round in the early 80's.
Fellow Marine Buddy/handgun nut from New York City loved them and stocked his Brownng P-35 AND two spare mags with the ammo(40 bucks of ammo in three mags!).
I have heard they are quite nasty on soft tissue, like a Liver....and they certainly made a way big mess out of a water filled milk jug.....
MagSafes.....are a very similar design..but uses a few larger shot mixed in with the smaller shot for a little deeper penetration.
Even back then, I believed in the thump and penetration of a good .45 acp round....so I personally stayed away from them, mostly...though I did load a .38 snubby with them on occassion, and used the Magsafes for my Makarov...when they first began to be imported(92-93) because there were no good JHP's out yet....Corbon came out with one soon after I sold the Mak(but I sold it because the safety gouged my thumb knuckle!).
Hope this added to you Edumication......

Sabots are also very common in shotgun slug rounds.

Sabot literally means a wooden shoe.Crap! I just had a flashback to when I last saw Star Trek 6!

"...workers threw their shoes, called 'sabot', into the machinery, rendering it useless........Hence the word 'sabotage'..."

I am such a geek.:uhoh: :scrutiny: :scrutiny:

What is that Glaser stuff made of anyway?:confused:
