Yes, you can get the same power as Pyrodex with a smaller volume of BH209. You can look at the websites for the manufacturers for data to compare. Also, that is why you can go up to 150 gr. volume of Pyrodex in modern inlines, but shouldn't use more than 120 gr. volume of BH209...and you will actually get more power with the BH209 at those charge levels. I would estimate the difference is about 10 to 15 percent.
If the Winchester primers you bought are standard shotgun primers, they should work OK with BH209. Just don't use the special muzzleloader primers, because they are milder than regular primers to help prevent the "crud ring" that 777 can leave in the breech after firing. BH209 demands hotter primers for reliable ignition.
If you order .429 bullets online, get the green Harvester Crush Rib .429/50 sabots to use with them.
