This might be true but... each rifle might be different. For that general of a statement I would disagree. I have a Black Diamond XR and granted they are talking about the Omega. Still, in my rifle with a shockwave 250 grain the best accuracy comes from 120 grains of loose Pyrodex. I have shot the 150 grain loads and accuracy could not compare to the 120 grain loads. Also the difference in accuracy from 120 to 100 grains made me a firm believer in I did not need all that recoil from the hotter loads.

Also the hotter the load the more chance of breech plug seizing, crud rings forming, a bad flinch developing, and the scope coming back and knocking the snot out of your forehead....[:@].

I would say test your rifle and you be the judge. What works for one might not work for you. Although the techs at T/C are pretty accurate most the time and are sure helpful with any thing you might need to know.

[&o] I can remember when the Black Diamond XR was the top of the line for the Thompson Center line of muzzleloaders... times and designs have sure changed.
