.303 Brit is .311 and .308 Winchester is .308 I think...

Right. The .308 uses :drum roll: .308" bullets and has a bore diameter measured on the grooves. The .303 uses .311" bullets but they measured the bore diameter on the lands... while the grooves measure .311". Which is more correct? But when I think "bore" I think what is the drill size used before the rifling is cut.

Back to the trivia. Who developed the .357 mag, .41 mag, and 44 mag?

S&W
I don't know any more specific than that. Was there any one person responsible?

If we're talking about the calibers or cartridges themselves (rather than the guns chambered for them), then the .41 and .44 were developed by Remington, while the .357 was developed by S&W and Winchester.

I believe Elmer Keith had a hand in all three.

General Patton's Trademark pistols were. A ivory Griped Smith & Wesson 27 .357, A ivory griped Colt .45 Model 1873 and a Colt 1908 .380 pistol.

cool, thanks!

Pearl or ivory handled something....can't remember... .38 revolver? nickel finish? Must be getting old (you, not me )

Gen. Patton carried a Colt 45 peacemaker AND a S&W .357, both with ivory stocks. Sometimes he'd carried them both

New question?

What is currently the largest caliber not classified as a destructive device under the 1934 NFA?

I believe it's the .50 cal??

 

[lawrra]

Too small

 

[OneBadV8]

Too small

Unless its the 50 cal on the Iowa Class...

Here is a question. Because I'm curious of the answer. What is the usual/common difference between he bullet circumference and the boring of the barrel? I'm assuming the barrel needs to be slightly wider. But by what amount? tolerance?

According to Wiki (might be flawed)

1. Any non-sporting firearm with a bore over 0.50" (many firearms with bores over 0.50", such as 12-gauge shotguns, which are exempted from the law because they have been determined to have a legitimate sporting use).

The bore is measured to the bullet diameter similar to the way the .308 is.

 

[Boilers]

So, is there any clearance built-in at all?
.308 bullet and .308 bore? not .3075 bore?

I'm sure there is a bit of clearance, but I haven't found any measurements down to the ten-thousandths. The projectiles aren't cast, but solid brass turned on a lathe if that helps. The rifle is a single shot, bolt action.

OneBadV8-
No, that's right. .50" is the largest caliber not classified as a destructive device.
Shotgun gauges are not calibers (except .410, which is .41 caliber.)

Nope. The .950 JDL (developed by SSK industries) fired in the McBros 95 is the largest rifle caliber that is not classified as a DD with a sporting use exception. Any 18 year old with upwards of $8,000 can pick up one of these beasts. The rifle weighs over 80lbs with a muzzle break over 10lbs. Projectiles are typically 3,600 gr, travelling at 2,200 fps with a muzzle energy of 38,685 ft-lbs. The casing is based on the 20mm Vulcan, shortened and necked up, at $40 a round.

Next trivia question:
How does one get a sporting use exemption for a caliber that would otherwise be classified as a destructive device?

An act of Congress?
