Mossy - Welcome again. And the only stupid question is the one you don't ask.
IMO, in a 50 cal., anything over 100 gr is a waste of powder. If you are shooting good with 100 grs then stick with it. I would try dropping down to 80 grs and try it.
When I had my CVA Optima Pro - I called CVA and asked them if it could safely handle 150 gr of powder (3 50 gr pellets). Their answer was 'yes it can but 2 pellets is sufficient. Any additional will be burned after the bullet leaves the barrel. I have a tendacy to agree with him as he was in the technical dept and not a salesperson. That is why I snicker when I hear guys putting 150 gr of powder in their MLs.
