On Jan. 24, 2007, H.P. White Laboratory Inc. tested the hardness of a CVA barrel to Rb 85, Rc 4 = 79,000 to 81,000 PSI, (depending on Hardness Chart, not all the same).
H.P. White Laboratory Inc. also tested a Thompson Center Barrel to be Rc 18 = 103,000 PSI.
Not really considering this from about 2007
As you read above, quoted from the H. P. White Laboratories report, the CVA inline guns tested were made from inferior, softer and weaker metal than an old Thompson/Center Renegade sidelock. So soft, in fact, that the CVA materials had to be measured on a different scale, the Rockwell �B� scale that is used for soft metals unsuitable for firearms.
Plus there is PROOF testing and hardness testing. Both are not always the same in barrel quality. Very hard steal can be brittle too. That is why CVA is not approved by CIP in many Euro countries and are banned in many of them without passing a in house proof test first before the consumer can take them home. Try buying one in Italy or Spain.
Call CVA and ask them how many retail outlets they have in CIP countries.
T/C has a list on their website.
Im not saying that i think new CVAs are unsafe for most loads but if they only tested them to
28k PSI as Gander said then a 3pellet load can be VERY dangerous.
