The problem is when someone comes along and tips up their box or unfounded beliefs they go to pieces and all rational behaviour diminishes.
Just imagine the pain that all those flat earth believers went through when the sphere they are standing on was revealed to them! It's just the same with this one.
Did you try it yet?
In addition to that, consider this....
If you think it won't harm yourself nor your gun, I'd say test it out. You can do so in a safe manner and truly see.
On the other hand, what could any of the rest of us offer? Anecdotal evidence if it went bad for one or more people does not mean it would go bad for you, as it would likely have been in a different rifle, different manufacturer. I doubt anybody has tested it in any sort of controlled setting.
In the 1940's they were using a little less than 10 grains of a certain type of
smokeless powder as the base charge in long range muzzle loading black powder rifles.
(iirc) It made for a very complete burn and really reduced the fouling. Now that particular formula of smokeless powder is no longer found, and I don't think anybody outside of Dupont or Hercules would know what pressures it created, IF they archived the data on that smokeless formula, so one could not make an informed decision to copy that procedure, nor should they try. BUT it was done and apparently with no ill effects to the rifles. (see
The Muzzle Loading Cap Lock Rifle by Ned Roberts) Today, nobody will tell you to even think of doing this....,
So things change over time, and folks adopt standard rules, especially in a litigious society that we now have. You're responsible for you, so I'd quit worrying about the rest of us.
