Why do BB guns only come in .177?
Is it an engineering issue (too much mass) or some other reason?
Link Posted: 7/31/2009 3:03:59 PM EST
Airguns are available from .177, .22, all the way to .50

I just read a story about a 50 cal air rifle dropping a MOOSE. I'll have to find it again.

think about the amount of air and pressure required to push a .177

Now think of the pressure required to

Ahhh... never mind –– you figure it out

.50, no report, no tax stamp.

that 50 is 600 fps now granted I wouldn't want to be shot by it but I would have doubts about any penetration.
Link Posted: 7/31/2009 3:43:50 PM EST
for that matter they even make airgun shotguns.

I'm pretty sure you could ramp that up pretty easily.

What was the muzzle FPS on a 1700's musket?

545grain at 1000 fps on a 68 cal Brown Bess over 100g powder some website so seems like 1k give or take.

well a 45acp @ 200grn is only ~850fps adv which would be from a longer than normal pistol brl, so i am sure it would penetrate

Didn't Louis and Clark have airguns for hunting? No need for powder to keep stocked or dry.

It falls to no market to sell such a creation or better options (centerfire rifles).
Link Posted: 7/31/2009 4:06:30 PM EST
So, yoozgyz don't know the stories of men caught with an air gun that were hung for just having them... a few hundred years ago?

da-da-damn, public education.
Link Posted: 7/31/2009 4:06:57 PM EST
I think the lewis & clark expedition brought along a .50 air rifle that had a bigass metal ball for air compression.

been around for a long time.

Yes, in fact the first fatality was a native American killed with that airgun.

Lewis & Clark took a large bore airgun on their famed expedition.

He said BB gun, not pellet gun. I've never seen a BB bigger than .177.

They're readily available in 6mm

Originally, BB guns in .177 caliber used what was then a very common size of (steel) Ball Bearing. It was very possible to make bigger "BB" guns, but there would have been no cheap ammo already in production.

BB had been standard bore of 0.175", originating from BB sized shot, used for waterfowl.

I've seen a South Korean airgun in 0.355" used for hunting boar.

Priced ~1000 bucks locally, supposed to shoot a 125 grain bullet at 1300 fps.

Aren't BB 's by definition 0.177 dia?

As far as large caliber air guns go?

Very Very big

Air Guns where making a name as war weapons in the time between Bow and arrow to Black powder.
They had better power than a crossbow and where quicker to reload
Black powder cut them short
I think France had some in their army

I'll Goggled and edited

In this era, France, Austria and other nations had special detachments of snipers who carried air-rifles.

The Austrian 1780 model was named "Windbüchse" (literally "wind rifle") in German. The guns were developed by the gunsmith Bartholomeo Girandoni (1744-1799), and are occasionally called "Girandoni air guns" in literature (the name is occasionally spelled "Girandony"). The Windbüchse was about 4 ft (1.2 m) long and weighed 10 pounds (4.5 kg), which was about the same size and mass as a conventional musket of the time. The reservoir was a removable, club-shaped butt; the gun was recharged by replacing the exhausted reservoir with a new one. The Windbüchse carried twenty lead balls of .52 inch caliber (13mm) in a tubular magazine. It could shoot one magazine in about thirty seconds, which was a fearsome rate of fire compared to the slow-loading muzzle loaders of the period. A shot from this gun could penetrate a one-inch wooden board at a 100 paces. The effect is roughly equal to that of a modern 9mm or .45 caliber pistol.

Actually, 0.172". Pellets fit the grooves, BBs are hard steel and must fit the land diameter which is 0.174".
