LCW 7.62x39 Nail Test

How is giving locals a good deal at a gun show a "problem"... Your probable just cranky because you missed out on the HAC show.

I bet you would be really pissed if you knew how much I payed for a Norinco single shot 12g from the Canam booth :), although I only hope to put another 50 rounds through it before it falls apart completely haha.

I was at the show so not a problem for me and why I know the price, however they do have a price match guarantee posted on this website.
 
anyhow, back on topic

Could some test data from the manufacturer or retailer be posted as to ptove if this ammunition is corrosive or not?

That's $300 plus tax?

Chris mentioned before about the show special prices at Chilliwack and HACS. Saves them shipping which BTW anyone knows how much it cost CanAm to ship a case?

Probably a cheaper price because like any tradeshow in any industry the tradeshow prices are typically lower or you could even throw in the fact that the company saves on shipping thus a lower price.
 
Could probably do that with a fish tank type kit

An alternate method would be to check whether or not the primers contain potassium chlorate which is a usual ingredient of corrosive primers. One of you guys who has access to a chem lab and the necessary smarts could take a sample of the residue left by the 'fired' primer and have it analyzed for the presence of potassium, quantity not important, just whether or not it's there. If it is, we have corrosive primers.

Perhaps this is a test that Can Ammo is, or should be, doing.

As you all know, it is the potassium chloride from a fired corrosive type primer which combines with moisture to potentially wreck the innards of a firearm.

My Understanding of the situation was that even though these primers are called "corrosive" they are are themselves not directly responsible for the corrosion The byproduct of the chemical reaction is a salt (Potassium Chlorate). This salt is hygroscopic and will absorb moisture out of the air, and it is the combination of salt and water and oxygen from the air which rusts exposed steel.

Almost correct.
The primer contains Potassium Chlorate ( KClO3 )
The reside left after it detonates is Potassium Chloride ( KCl ), very similar to ordinary table salt, Sodium Chloride (NaCl )
Worth noting, KCl is not at all soluble in ammonia, so ignore the Windex nonsense.
http://en.wikipedia.org/wiki/Potassium_chloride

Solubility of KCl in various solvents
(gram KCl / 1 kg of solvent at 25°C)
H2O 360 grams
Liquid ammonia 0.4 grams
 
We'll have the report in the next day or two from LCW

If I can find a lab that will test explosives in Canada, we will do a proper test as well
 
Shot 100 rnds of HP two weeks ago, from range to case to safe, just checked it, no sign of rust, looks exactly same as with shooting MFS for last several years. Everyone knows what the weather has been like lately in the Lower Mainland, yup, swamp city. So unless rifle shows signs of rust which isn't expected will treat this LCW ammo as non corrosive.

Luv the XCR, so easy to disassemble.
 
Yes thx for the correction ,I had the products / reactants mixed up,

Instead of needing a lab that will test explosives, I suggest the following testing method:

1. Get a bolt action rifle which has been thoroughly cleaned, preferably one which has never fired 'corrosive' ammo.
2. While wearing latex gloves, run several clean patches through the bore.
3. Keep the last patch and place it in a new plastic 'baggie'.
4. Fire several rds. preferably from different lots, or at least different boxes, through this rifle.
5. Run a clean patch through the bore and place this dirty patch in a new 'baggie'.
6. Have a lab analyze both the clean and dirty patches for the presence of potassium and chloride. Perhaps the easiest way for the lab to do this would be to place the patches separately in distilled water and then analyze the water samples for potassium and chloride.
(there are water testing labs in all provinces)
The presence of potassium and/or chloride would indicate that the ammo primers were of the corrosive type.

* The limitation of this test is that it checks for the presence or absence of the chemicals which were/are used in common 'corrosive primers'. If someone has produced a newer type of 'corrosive' primer which contains different chemicals which could be corrosive, this test will not find them.
