Well, the only way to really prove a rifle went tits up because of conditions is if the same person was carrying 2 different rifles at the same time under the same conditions, in the same manner and one failed (browning) and the other one didn't (take your pick). Not a very realistic scenario, but more proof positive.

BTW, I am not a Browning fan boy nor a detractor. The few that I have owned have been out of box accurate and reliable.

Faith and love of others knows no mileage nor bounds. That's simply the way it is.
