LCW 7.62x39 Nail Test

Waiting for CanAm to ship my FMJs. The HP took 4 bus. days couple of weeks ago. The FMJs still hasn't ship in same time, CanAm must be getting busy again.

Make you own bullet puller as long as you have a shell holder and a piece of 2x4 and drill bits.

lol. I am waiting for Canpar to drop it off

And can you lend me a bullet puller?

You need a control group for the experiment to be legit. I know it looks legit, but you still need a control group. I was thinking of doing the same experiment myself with my four brands of ammo, with only the S&B being non-corrosive. This thread is very interesting even without the control group. Thank-you for sharing.

Well I did actually have a fourth nail with no primer fired on it but I didn't post pictures because it still looks exactly the same as the "before" picture of the LCW nail. I figure why waste the space. Same reason I didn't post before pictures of the other two nails. This isn't exactly for a scientific paper. It would just be redundant to post more pictures of shiny nails.
 
How were the nails prepped and what conditions where they tested in? I ask because it's entirely possible a clean uncoated nail might rust as well if left, or exposed to a minor amount of heat.


ALSO what order were these fired, and how well was the gun cleaned between firings? A corrosive round before a non corrosive round will carry the corrosive round's residue with it and contaminate your results.

Ideally, fire one kind of ammo from 3 different guns. If this isn't possible, fire the S&B, then clean the whole gun very heavily through whole gun/gas system/action, then LCW and clean heavily everywhere, then the chinese stuff. This will reduce contamination, but still won't be perfect. Also get a control nail and treat them all the same with cleaning, prep, handling and then keep them far away from each other so when the testing is done there's no contamination from A) firing and B) proximity.




I ask all this because this is something that could majorly impact canada ammo and should be done properly.
 
I encourage other people to test theirs and post results because one test doesn't necessarily condemn the whole product line. It's not a difficult test. Just have to spend a small amount of your time.

There is no firing of any guns during a " bright nail test"
 
Firstly Thanks for the effort. It is this kind of extra that makes CGN a great place.

How did you fire the primer? Assume not in the gun. Hold casing/primer over the nail, hit primer with nail and hammer?

Once my FMJ comes if it hasn't been resolved I have the LCW FMJ, HP and MFS that can be tested.

I didn't use a gun, I used a punch and a hammer with the cases right on top of the nails, and I did it in the order of S&B, then LCW, then Chinese. The conditions are in the original post, dry Calgary air, spent about half an hour on a bathroom counter while I showered on the other side of the room, two days in a row.

I agree it can majorly impact Canada Ammo, it could also majorly impact people's personal property, like a $2500.00 XCR. That's why I'm not pointing fingers, I'm merely drawing attention, and it's quite easy to test it yourself, the more the merrier. I'm not a scientist so perhaps there are variables I may not have accounted for. But as far as my knowledge goes it was a good test. I don't exactly have a laboratory.

Yeah I used a punch and hammer over the nail. And yes! It would be great to get some other test results here, I'd love for mine to be proven wrong somehow.
 
I appreciate the few of you folks with supportive words. I was expecting kind of a backlash, knowing how much love people have for Canada Ammo (including myself). I didn't post this to drag Canam through the mud, but it's something I think people ought to be aware of. IF other tests do come back suggesting more corrosion from LCW then I'll have done a good thing bringing it to light. If more tests come back and show the opposite then we all can know for sure, and I'll be buying more. So I see it as a win-win. Either way we'll have learned something, and when I get a little more time, I'll try another test and see if the results can be repeated. When I do I will post the results here.
 
How loud was the primer when it went off?
Did you need to wear ear protection.
More importantly is it loud enough to freak out the neighbors? I'm smack in the middle of Lower Mainland two blocks from the RCMP station so don't need a visit.
Do I need to do this at the range or where legal discharge is permitted?

I've done it with Chinese and Czech 7.62x39. It's not too loud, though the primers can be pretty hard to bang off! If you're in a garage in a detached house your neighbours won't hear anything louder than a hammer bang.

I didn't wear hearing protection and was fine. You're NUTS if you don't wear eye protection.

You're not shooting a firearm, so I don't think you would require "legal discharge". That said, I'm no lawyer!

I wore hearing protection AND eye protection. Just as a precaution. If you've got good ears, it might be uncomfortable to hear indoors, I'd wear it, it can't hurt. I'm glad I wore eye protection though because the S&B primer was ejected out the back and gave my quite a forceful sting on my finger. Left a blood blister. Your eye wouldn't fare so well. Maybe wear gloves too ;)

As for legal ramifications, I can't say for sure, but I think you would be hard pressed to convince anyone detonating a primer is equivalent to firing a cartridge, so I don't imagine any legal troubles. No one outside will hear it though anyways, it's not nearly the same effect as a gunshot. And no one would mistake it for one, so I wouldn't expect any RCMP to show up.
 
Also I should note that I left ALL of the casings ON the nails during the entire test period(which is still ongoing), only removing them from the nails to take photo's.
