There was a fella in Australia that posted, I cannot remember his name or whether he posted here or on AR, or both, that split the solder on the barrels of his 9,3x74R Chapuis shooting Barnes bullets.

He sent it back to Chapuis to be fixed. Then split it again, also shooting Barnes bullets and again sent it back to be fixed a second time.

He reported they asked him what he was shooting, when he told him Barnes, they told him not to shoot them in his Chapuis 9,3.
