CSI: Decoding Shell Casings

[@ksrebelbuck7936]

Side note on shotgun shells, a quick way to know roughly what kind of ammo was used can be identified by the crimping on a spent shell, if it's wrinkled looking or like a crown at the opening then it was multiple pellet shot either birdshot or buckshot, if the opening is smooth all the way around that's a roll crimp and more than likely the round used was a solid slug, it's not a guarantee but 95% of the time it will be the a reliable identifier

[@BlackWolf18C]

Speaking of pistol cartridge casings, if you look at the primer dent it is sometimes possible to immediately identify the type of firearm it came from because of the backpressure inside the casing pushing material into parts of the gun. Glocks will leave a rectangular raised shape around the striker dimple, and the S&W M&P series will leave a teardrop shape.

Very interesting learning video Tommy always enjoyable

Nickel plated, ammo besides duty use could be a alleged citizen self defense shooting, lots of people carry small 9mm handguns and choose to carry any number of specialty hollow points.

[@freefieldtraining]

Same same

[@daddybeagleaz907]

​@@freefieldtraining I bought some carry ammo recently from Federal which I felt sure would be in the nickle plated cases but turned out to be brass....

[@thadrobinson8343]

@@daddybeagleaz907 Might depend on the production run? I've bought the "same" Hornady ammo (same name, same box, same product number) and while most boxes were nickel plated some were brass.

@@thadrobinson8343 that's what I was thinking, thanks

9mm Parabellum is the proper name of the caliber. 9mm Luger is a 9mm Parabellum loaded to standard pressure. 9mm NATO is a type of 9mm Parabellum that is 8:40 loaded to modern military standards and is a slightly more powerful loading than standard pressure (AKA 9mm Luger). 9mm +P is probably (most likely) but not necessarily a more powerful loading than 9mm NATO. It can be up to 10%more potent than standard pressure (9mm Luger), but not every manufacturer will push the envelope that far. For this reason, it can be argued that 9mm NATO is a type of +P round too, and technically, it is but it's power levels are more strictly defined than the generic +P designation which is somewhere between 1% to 10% more powerful.

You can smell a freshly fired case

[@samwilliams1142]

I load my own 410 and 12ga shells. Some slugs use fold crimps, some shot charges use roll crimps. Some slugs set inside shot cups and some buckshot use felt and cardboard wads no shot cup.

[@niccosaur7778]

Exactly

[@russhamilton3800]

Nice, I have been passing this stuff on

[@jeffhuntley2921]

21:59 palmetto state armory has 5.7 Rocks for sale for under 400 all the time. That’s less than a new Glock. Range bullets are 43cents a round which is only a bit more than 9mm depending on what you shoot. Cheers

[@kevinrichardson8859]

At 11:55 that's a 357 magnum casing and not a 38 special casing...357 is a longer casing than 38 special...amd 357 mag and 44 mag are approximately the same "length " (casing)

[@venz8201]

@12:29 he corrects himself

[@Messier87_M87]

Do you ever come across any cases with crimped primers?

[@fidel-3470]

Great video - I'm surprised you didn't show casing made of Aluminum (Blazer) or Steel (Tula) ammo, as these ammo types are by far the least expensive. These are not shiny like brass. These are going to be often found in 9mm, .223, and 7.62x39. It's ammo intended for training purposes, known for not being reliable, so if you find it on a crime scene it's indicative of someone who has no idea what they're doing with firearms, the opposite of a nickle casing: they don't know anything about self defense. I would presume this was the cheapest gun a person could get on the street, almost certainly bought illegally, and very likely a juvenile.

[@Razor-gx2dq]

Yeah steel case is dirt cheap, I don't even bother to buy it for training purposes anymore, maybe its just the batch I bought idk.

[@KahshinLiu]

Yeah, i too was surprised by him not showing the most likely rifle round (7.62x39) at all or steel cased 9mm ammo. But its a flat out myth that steel case ammo isnt reliable. Only in poorly lubricated AR-15 pattern rifles & budget handguns is steel case ammo not reliable. Ive put nearly 1000 rounds of steel case through my budget AR & my first time bringing it out it jammed alot. Then we soaked it with CLP, it broke in & it now feeds several mags without a problem. My duty pistol ate many tulammo & wolf without one malfunction. In AK's & my SKS i couldnt tell you how many steel cased ammo rounds ive fired over the years.... Easily thousands. I will say that steel cased .38 spl in revolvers is truly a terrible idea. tldr; ive personally been present at shootings where guys with Dracos fired steel case. They work

[@niccosaur7778]

Lmfao

[@interstellarsurfer]

He doesn't show that - because it doesn't tell you anything. Everyone uses the cheapest ammo for crime.

[@joshmiller9783]

Yea you might be the one who knows very little about firearms and self defense.

[@AteuCu]

Thanks, that was great as always!

[@tombats6428]

Bottleneck pistol rounds include 22TCM, 357 Sig and so on

[@BiggYTRAIDER]

You forgot 357 sig in the bottle neck rounds.

[@rogerray7820]

You should go get the velocity book out and check out 12ga, 16ga, 20ga, and 410 velocity. You'll find the velocity is the same for all of them --- around 1250 fps. The difference is in the weight of the shot . You can every gauge in the same shit size just lesser amounts in each.

www.remington.com/shotshell/slugger-rifled-slug/29-28600.html It's not the 1800's anymore

[@cornpopwasabaddude4188]

Sweet

[@ksrebelbuck7936]

I'm sorry but ALL police officers on patrol carrying a firearm or investigating a crime scene should be very educated and familiar with firearms, it shouldn't have to be learned by online videos on their own time, but this is a very educational video good for training, also something to touch on as far as old casings is brass tarnishes, dulls, and discolors over time, so if you find a casing that's brown/black it's very old, at least a few months old, these are just for brass cased ammo, however you can run into aluminum, steel, and zinc or nickle plated casings so they'll tarnish differently over time

[@freefieldtraining]

I agree. But, then again, in an ideal world we wouldn't need police at all so here we are.

[@ksrebelbuck7936]

@freefieldtraining no I'm saying departments need to be funded more so they can train their officers on these things, it's nothing against your video or anything like that, it's what the federal government has been doing to departments

[@Ruby_Sterling]

Gun guy here. I’m familiar with all of these.

[@ksrebelbuck7936]

Also .22 short isn't common at all anymore, .22 long rifle and 9×19mm (9mm Luger) is the 2 most common calibers you'll see, not trying to undermine the video just helping you give the best info for new officers

[@samwilliams1142]

Military surplus may have just numbers no lettering.

[@sharonrigs7999]

So in other words......use a wheelgun or SxS/UO non ejecting guns 😅

[@upholdthesecond92]

Ballistically, how do you match up a casing to the gun?

[@niccosaur7778]

You can't that's not real

[@kevinrichardson8859]

Thats not true...but definitely not going to explain how its done here as this should be information that shouldn't be broadcasted

[@kyledawson4535]

That is an extremely complicated process. But you can most of the information online.

[@roykiefer7713]

A ‘shell” and a “cartridge” are not synonymous. These are “cartridge casings, not “shell casing.’’

[@niccosaur7778]

Some very limited very basic calibre recognition info and also some very poor and incorrect info

[@sambowz9077]

🤣🤣🤣

[@Ruby_Sterling]

FN 57 is super overrated.

[@Dead_Again1313]

Why? Just curious to know your opinion. I used to have one, but the ammo was expensive and the lack of variety and availability kind of sucked.

[@kevinrichardson8859]

Thats one of the reasons its overrated...it also isnt much more ballistically superior than a .22 magnum fired from a carbine...would you be satisfied with that energy level and ballistics to stop a "determined " opponent? I wouldn't

[@tombats6428]

Not very informative. Old info.
