Deputy,
When Hodgden brought out Triple Seven, they recommended that a reduced charge of 15% Triple 7 as compared to Pyrodex. If you are currently using 150 grains of Pyrodex, a charge of 100 grains Triple 7 should be right.

Deputy

Any charge beyond 120 in loose powder is a waste of money & bullet because the last 30 grains will not burn and you will most likely see reduced accuracy -- most times, not even hitting a large target 125 yards away.

The whole 150 grain hype revolved around velocity increases that manufacturers got kickbacks on from bullet companies who boasted 2600 fps.  Yes... the bullet will fly a little faster between 120-150 grains, but that's due to increased pressure in a bore that now has to push more depth of packed unspent powder along with the tight-fitting sabot/bullet.

A 110 grain Pyrodex Select charge with a 300 grain rifle-looking sabot/bullet will drop a moose at 150 yards. Anybody that shoots a ml beyond that is a very good shot with a very good rifle/powder/bullet /weather/terrain combination.

Deputy,
According to Knight you can use 120 gr loose or 150 gr in pellets in the magnum rated guns. Being that your shooting a Disc Elite, your Ok if that's pellets. That's per the manual.

Of course, according to my contact at Knight only about 130 gr. (loose) will burn depending on gun. They tend to overkill on the testing. My kinda people! :grin:

I have a Disc Extreme and with the 250 gr Barnes and 100 gr of loose T7, I get muzzle velocities 100 fps slower than 150 gr of Pyrodex pellets will. The best part is that my shoulder doesn't take the pounding with the 100gr. T7 that 150gr of pellets will do.

Wheeww, 150 grains of powder. My state doesnt issue elephant tags  :)

I'll go with tripple seven and wolfehound on this one. probably more than 100 grains is a waste of money for the return you get for the extra charge not to mention the possible safety issue especially with all of the old sidelock guns around. Just because you can dump that much powder down the barrel doesnt mean it is needed. I have seen guys put those type of charges in older guns just because so and so uses it in his gun and when it recocks the hamer they get all excited thinking how much more powerful this load his friend gave him is! :shock:
The law of diminishing retuns still applies for BP.
With 70 grains of 3F or 2F  under a thompson style maxi ball dropped from my own mold in my old 45 cal mountain rifle I have taken many deer. The maxi ball has never stayed in a deer yet and a couple of those shots were a little beyond the 100 yard mark.  
Just a little food for thought here :grin:
