Cimarron,
There are not to many loads that you can shoot in a muzzleloader that stay under the 10,000 # mark. Most any load you shoot is over this amount of pressure, usually double.
Like anything else in this world, there are different qualities to most anything built. Just because one Spanish barrel failed NOT all Spanish barrels are bad, even if one barrel failed not all barrels from that manufacturer are bad. GM and Ford would really be in trouble.
The proof mark you find on your CVA/Traditions barrel indicates that the House of Elbar has proofed the barrel to that standard. That standard is also the minimum standard set to be able to export a barrel from Spain. The Spanish proof house will proof any barrel to any pressure you want if you pay and increased price for each level of testing. If you wanted a barrel series tested to 100,000 #'s they would attempt it but you will pay an additional price. Of course that price will be passed on to the consumer, and I am not saying that is bad. The company that manufactures the barrel must submit a barrel to the proof house every so many barrels to be proofed once it has been proofed the manufacturer can ship XXX number of barrels from that test and the stamp is applied to that run.
CVA, Traditions, and A&H all use Spanish barrels, they feel they need level of barrel proofing to help be competitive for their pricing of the gun. It is my understanding that A&H has since switched to a higher proofed barrel. CVA and I am not sure about Traditions have stayed with the minimum. Niether BPI (CVA) or Traditions actually build their guns, that is done in Spain - these two companies market the product in the US. We, us consumers, HOPE that both of these companies have insisted on further pressure testing by the manufacture. In todays lawsuit happy U.S. I am certain they have and further I would bet there is binding document in the contract that says the barrel will stand up to the loads published in both companies manuals. If you exceed these loads the liabilty no longer becomes theirs. It is also my belief that if these barrels are/were blowing up because of a manufacturing defect the law suits would have wiped these companies out by now. Be sure they, probably both companies, but CVA for sure, have had law suits filed against them for rifle failures - but so far it does not seem anyone has proven it was the manufactures default. I am sure that all of this debate has hurt their market share and that is another objective of some of these claims and suits - they are not American made. And that opens a whole 'nother can of worms.
I for one thinks this debate has gone on long enough, but one man continues to drive it and he has convinced several others - some Spanish barrels are weaker than others - that is a fact, but some Itialian barrels are weaker than others, even some American barrels are weaker than others.
I truly believe this will go on forever....
