I don't think Jumpshot was trying to pick a fight or even make an unreasonable statement.
Reading the opening line of the post he was referring to I read:
"The three shot deal is about obduration to the point of failure. You can bend/strain/move a piece of steel within its fatigue limits for a large number of cycles."
This is saying (quite correctly) that a material can be subjected to excess stress more than once before it fails. Notice the "can be". If the stress is high enough, if can fail on the very first try.
The post he was referring to goes on to say,
"You can fire smokeless in a ML *once.* Maybe twice if you are the lottery winning type. Then it is a wall hanger for all time. Or a bomb. "
WE know the author was not meaning to suggest that someone can use smokeless powder safely but there are all sorts of people on our forum with all sorts of knowledge and experience.
There might even be a few who know absolutely nothing about gunpowder/smokeless powder/strength of materials/failure modes. (I know. Hard to believe. :grin
.
Anyway, IMO, posts that
could be interpreted incorrectly and this incorrect assumption
could lead to harm should be commented on "to protect the innocent", so to speak.
