I prefer it in writing. My Savage manual has BH209 load data in writing. If something goes wrong, what someone said on a phone call is too easily debated in court. Knights current BH209 data says 120gr. I dont care what they say about T7 pellets. Its not the same powder. Would you reload a 45/70 with a powder that is similar and use the same data?
In writing its solid and officially approved by the manufacturer. CVA recommends 3 pellet loads that exceed 110gr loose powder pressure and even exceed what YOU said their barrels are tested to in PSI. They should be slapped silly for that one considering a single mistake with T7 pellets can reach over 30K psi easily. That makes me feel really safe in a 28K psi tested barrel.

A Magnum Load of 3 X 50 grn.(150 grn total) pyrodex pellets or 100 grn. loose powder (FFg) has a peak PSI pressure of 25,000 to 27.000 PSI, (may be as high as 45,000 PSI?).
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.

Does this make you feel better?

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.
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.

Bellm has tested the CVA barrel hardness and they passed with flying colors.
Not sure how we got onto this when it was about you guys shooting unapproved powder charges?
CVA allows 150gr Loose powder max.
