Powder recommendation from a Manufacturer are always set low for liabilty sake. They have know idea what rifle you may be shooting or the condition of that rifle. Hodgdon recommends 100 grain max of T7 also, but the rifle manufacture recommendations are the ones to follow for that particular rifle. And you will find that most ML manufactures are always above the powder company reccomendations, because they have done the testing in their products.

And I hope you do not think Grouse is the only one shooting 140 grains of BH in there Knights.

When in doubt - get your rifle manual out and see what it says.
