Canadian proof house for firearms and barrels

I don't think we have such an organization, it is up to the manufacturers to test their firearms and make sure they're safe, seems to work this side of the pond.
 
No such organizations exist, as there are no requirements for Canadian firearms to be proofed. Some countries require all barrels to be proofed, even for rebarrel jobs, but we do not.

Why would you want to damage a new firearm? Proofing is an intentional overstress of the barrel. With metals, all stress damage is cumulative. Just cause a bbl survived an overpressure round, doesn't mean it won't blow up sometime down the road with regular rounds.
 
The only 2 major manufacturers I know of in Canada are Colt and Savage. Savage just does rimfires here, so I don't know about those getting proofed...?
Colt HPT's and MPI their rifles.

The stress wouldn't be cumulative unless it passed the yield strength of the metal.

Below that there should be no issue.

Both Colt and Savage are members of SAAMI which is the North American industry association responsible for proof standards.

Got me thinking on another tangent: is a 'proof mark' considered a 'trade mark'?? If it is and someone faked a proof mark... would that constitute a trade mark infringement? Or are there separate laws governing the improper use of a proof mark? Just curious.
 
I'm asking as I was thinking of building a percussion pistol for personal use and not resale. You have confirmed my understanding. That Canada doesn't have a proof house. I'm currently at a shooting competition in Europe and some countirs require all firearms are being shot to be proofed even antiques. They don't necessarily proof to maximum loads but a set charge and a then a double charge of it (blackpowder).

I believe that there are laws relating to the faking of Proof Marks in England. Am I sure? No. Proof Marks are not a Trade Mark, they are essentially a certification of fitness for use, by a Government appointed agency. Like as not ( a pure supposition on my part, this) they would fall under the Laws relating to Forgery, if there are not specific laws that relate entirely to Proof Marks.

The Whole Proof House concept is tied in to the use of assorted cottage industry manufacturing methods to make guns and gun parts. With essentially no control over materials or methods used, it was a logical construct to ensure that the firearms were fit for their intended use.

Not a thing in North America, as by the time folks started worrying about that likes of that, the manufacturing of firearms was essentially a factory affair, rather than piece work. Steel came from a mill, rather than from a blacksmith forge welding leftover bits and pieces together.

Buy decent quality steel, or better yet, a barrel made by a reputable maker, don't try to cover any new ground as far as design criteria goes, and you can reasonably expect to produce safe firearm.

If making entirely from scratch, buy quality known steel, and a calculator, and sit down and learn what you need to know about pressures and hoop stresses, etc., so that you can design a factor of safety in to your work.

As close as we get to a Proof House here, is "Have a gunsmith go over it before using". If you can find one that knows about more than where to look up the mounts he needs to stick a scope on it.

There are specific laws in the UK regarding forgery of proofs.

http://www.gunproof.com/Proofing/proofing.html

The Proof Acts lay down that no small arm may be sold, exchanged or exported, exposed or kept for sale or exchange or pawned unless and until it has been fully proved and duly marked. The Maximum penalty is £5000 for each offence, but with provision for higher penalties where, for instance, the sale of a number of guns constitutes one offence. Alteration to or the forging of proof marks is a more serious offence.

Arms previously proved and bearing apparently valid proof marks are deemed unproved if the barrels have been enlarged in the bore beyond certain defined limits or if the barrel or action has been materially weakend in other respects.

Anyone with lots of time on their hands can read the entire UK proof legislation here.

http://www.legislation.gov.uk/ukla/Vict/31-32/113/introduction

There is also the C.I.P. (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) which allows for mutual recognition by proofs of member countries.

http://www.cip-bobp.org/

The proofing system in the UK is desirable because it applies to any gun that is sold and is taken very seriously. Here I've encountered many guns being sold that would be considered out of proof in the UK and C.I.P. countries. Caveat emptor.
