We had a similar thread a while ago.
The topic of proofing = Safety was brought up.
http://www.muzzleloadingforum.com/fusionbb/showtopic.php?tid/217920/post/531858/hl//fromsearch/1/
I add the below quoted post to that thread.
As further information since then I have acquired a CVA muzzle loader that has a barrel marked “Spain” and no proof marks.
So not all European guns are proofed.
“This thread has drifted some what.
If possible I think I can summarize some points that I have learned from this thread and others.
- No US or Canadian gun is proofed
- No Japanese gun is proofed
- No Indian Gun is proofed
- No South American Gun is proofed.
- Only Western European guns are proofed if they are to be sold as guns in Europe.
- Some High-end gun makers in the US will "Defarb" their products going so far as to add European proof marks to make the reproduction look like an original. Even if the weapon was not proofed.
- Proofing will not tell you if the gun will fail. All it will tell you is that it did not fail once, at the proofing.
- Many people swear that they will only use proofed weapons unless their "friend" made it then its safe.
- There are no international Proofing standards. In other words, it may have passed proofing in one country and could have failed in another.
This is an interesting topic that we may need to pay more attention to as users of the product. The US may institute some form of proofing some day. This would probably hinder the small builders out there who would see another layer of government regulation and taxes added to their business. Currently Muzzleloaders are relatively unregulated. If we start requiring all weapons to be tested by the government and marked as such we will be starting a regulatory process we may not like.
