500sw mosin

I have had 3 guys send that to me; that guy in the video is an idiot and has NO idea what he is doing and neither do the others in the film.
And putting an AR-15 magazine in a Mosin Archangel stock; please....No wonder it fell out. And of course it has a safety!
Same energy as a 338 Lapua? Seriously?
It is crap like this that gives shooting a bad image.

I only could watch until the mag fell out. Those guys obviously know zip about ballistics. A short fat pistol cartridge equivalent to a 338 Lapua! Wow.

they are entertainers, and make stuff up -- but they do usually entertain

I have no patience for watching those idiots.

But muzzle energies from lets say 20" barrels could be comparable. Something like 5300 J from .500 S&W to 6000 J from .338 LM.

For 16" barrel, it is about 5000 J compared to 5250 J.

If .500 loaded to length over specs, it will be equal from shorter tubes (the same muzzle energy).

We use Foot Pounds; only .0001% of Americans even have heard of a Joule. A Newton Meter??? We don't use Newtons or Meters either.
One Joule is .7 Foot pounds.
A 500 S&W produces 3000 Ft Lbs. From a longer barrel? I have not chrnograpned one.
I do know that I watched a friend shoot a hog in October and it blew out half its liver and made about a 4 inch hole in the process.

Newton Meter is a measure of torque...

Longer barrel .500 S&W ballistics with factory ammo for example here: https://www.outdoorlife.com/ar...hunter-rifle-sw-500/

I have only revolver in .500 S&W, but looking for the rifle too. Some people here have some cheap break open .500 single shots and chronographed crazy velocities. I just missed TC 500 SW when it was on the market.

I use load with 44 gr H110 and 400 gr Woodleigh bullet. It is chronographed from my 7.5" barrel revolver at 1644 fps and QuickLoad says 1638 fps. It is 50k PSI load, not anything close to max. (It is max for me in the handgun because of stout recoil).

When I change barrel length in QL from 7.5 to 20", it says 1995 fps and 3536 ft-lbs.

For 46 gr, it says 2070 fps and 3807 ft-lbs

With LilGun, you can get even more velocity, but I don't use it in the revolver for that "flame cutting" rumors. And it is true it heats up things fast:

LilGun is great for TSS loads in 12 gauge 3 1/2" shotgun. 2 1/2 oz load in O/U shotgun is not for recoil sensitive shooters. But barrels get hot incredibly fast.

All the 500 Mosins I built have 23 inch barrels.
And yes, I know what Newton Meters are; I said that no one here uses the Metric system for anything but to weigh Kilograms of Cocaine.

BTW for example metric system was used for Apollo space program. Doing scientific calculations in Imperial system is just pain in the ass. It is almost like doing math with Roman numerals ;-)

Jiri

I graduated in chemical engineering in 1972. We used the metric system until the last year when the professors started using imperial units. We asked why, as we were quite comfortable with metric. The answer was because none of your employers use metric. And they were right.

Jiri: come over and talk to any American you see; most of them do not work in the space program, and have no useful knowledge of the Metric system. Sure, they are taught it in school, but we, as a society, do not use it and it is quickly forgotten. A Meter is like a Yard, sort of. A Kilogram? No idea. Newton? Didn't he invent gravity?
Tell any American that you like a temperature of 25 degrees C.
They will look at you like you just dropped in from Mars.
As Vol gave an example of.
I assure you there are no members of the Apollo Space Program anywhere near here. Maybe in Houston.
I know this is hard for others to comprehend; it ain't going to happen. In 1795 Benjamin Franklin recommended we go to the Metric System, but it was going to cost too much.
Soda Pop comes in 2 Liter bottles; that is literally the only exposure to the Metric system most will get.

Amen Tom!

Got news for you dpcd: Most Americans don't know squat about English weights and measures, either. The ones that watch football have a vague concept of what a yard is (or at least what it appears to be on TV), but outside of that they can't guess at an ounce or tell you how many feet are in a mile, much less have any concept of what size .308" is. But now that American liquor comes in 750 ml and 1.5 liters they're catching on to metrics to a small degree.

But still don't ask them which ocean you cross to get to Spain or what a Prime Minister is because they'll give you either the wrong answer or a blank stare.

Darn good points briught up here...but I'll bet a Big Mac these same arguments will hit a dead end 50 years from now Old guys like me rmermber the attempt to go metric many years ago. Road signs were in miles and KM.

One can only imagine what a streamlined America could be if we just didn't firmly believe the rest of the world is out of step.

Got news for you, booze has been metric in the US for almost 45 years.

Yeah, you Americans have an average math skill level. of a 6th grader; ranking 26th out of 38 industrialized countries. Probably a good thing you can measure your liquor.
This is not anything to be proud of....

Australia went metric 50+ years ago and it certainly makes arithmetic easier. However, yours truly grew up with imperial and still thinks that way for many measures, depending on which seems easier at the time.

I still zero and estimate shots in yards. Being vertically challenged, my paces are closer to a yard than a metre. If someone mentions metric calibres, esp. the 8x57, I like to know what the groove diameter is in thousandths of an inch. Though I might measure case lengths in mm, I'll continue to weigh powder in grains avoirdupois and measure case expansion in thous.

We went metric in the UK years back, yet a lot of our road signs still show miles.
Just to be bloody minded I often combine Imperial and metric, like cutting a piece of ply 9 inches by 728mm.

Mosin's are not my thing so I have not looked at this thread in a while. Boy, it sure took a left turn somewhere.

John

Back when I had my 03 FFL, I bought several Mosins for $69 each. After opening the case I thought, my God, what an ugly rifle, and promptly gifted them to several friends.

Now Tom is building me a custom Mosin in 405 Grenadier. Really looking forward to it.

I run a FB page for the 375 H&H. A few years ago some knucklehead had the ultimate bubba rifle - a modified AR-15 receiver shooting a 375 H&H (not from the magazine)

Now, you are probably saying not possible, how would it fit, etc etc etc. Well, that's what we couldn't figure out either from the pics - more welds than a battleship with stuff sticking out everywhere. Everyone responded saying the guy was going to kill himself. He posted some other stupid, dangerous stuff and we banned him.

I just searched for the pics, couldn't find it - probably because we banned him and removed the content.

There are clearly no auto mechanics contributing here. Im still trying to find that damn 10mm socket I lost 40 years ago. what a PITA that was expanding tool sets to accommodate the influx of crappy Japanese cars of the 70's.
I wonder how many Europeans are well versed in the inches/gallons/miles system? And does it mean they are stupid if they are not?

Tom is so worldly that he has a tape measure that operates in cubits and dates his favorite rifles by measures of lustrum.

biblical, roman, or Egyptian cubits ?
