has anyone ever shot the 2 side by side?

I believe the magnum 777 pellets are roughly equal to 3 of the regular 777 pellets. In terms of loose powder, that would make it equal to about 120 - 130 grains of loose 777, if I'm not mistaken. Though it does make a difference if you are shooting FFG or FFFG powder. But for the life of me, I can't see the need for anything more than 100 - 110 grains of powder. I've gotten some of my best groups with 70 grains of 777, and my hunting load is usually around 90 grains.

My first BP deer several years ago was shot at 100 yards with 80 grains 777 and a "puny" 200 grain bullet - it dropped as if struck by the hammer of Thor.....

I have found that 150 grns opens my groups significantly
And for the game that I hunt here in the south I stay between 80 - 90 grains with 200 - 250 grn bulletts.
For larger game I would most likely go 100 - 110 and heavier bulletts or whatever powder charge was correct for my bullett choice.
Plus,I am not a fan of heavy recoil.

Heres my experience with 150g of trip 7....It will be consistent one minute and throw off the next.....Then check out the 100g charge the CVA Accura loved it!

Here is the quote from the 777 website:

The newest entry in muzzleloading from Hodgdon Powder Company is the Triple Seven Magnum Pellets. With two Triple Seven Magnums you can acheive an additional 200-250 fps. In 26" in-line barrels this will normally result in muzzle velocity of approximately 2,000 fps.

That means that it brings up the velocity from about 1750-1800 fps to 2000. That is at most a 15% increase. So 2 magnum pellets should be equal to about 110 to 115 gr of blackpowder equivalent. That is also what 100 gr of 777 loose is capable of .

I don't think there is animal on this continent that could stand up to that load - at least not with a decently placed shot.

with that load and distance, the animal would have enough time to stick its tongue out at you, flip you the bird and run away before the bullet got there LOL j/k

If my guesstimating of the velocity is close then the drop when sighted in for 100yds would be 25 inches and the time to impact would be .5 of a second.
If the animal is standing still and relaxed it won't take more than one step in that time, the amount of drop might give some people hiccups. Lee

Just for comparison my favorite load with the 200gr Lehigh and 140 gr of BH has a flight time of .3 of a second and sighted in at 100yd has a drop of 7.5 inches.
The big advantage is that I sight in for 2.5 inches high at 100yds which puts my dead on at 170 and only 3 inches drop at 200.
I was surprised that there was not more difference in the flight time, of course the heavy bullet holds its velocity better even though it starts a lot slower. Lee

Just to add my $.02 worth....I'm not that much of a BP shooter, although I do own three of them. My go-to deer rifle in the "any muzzleloader" season here in PA is my CVA Wolf shooting two 50 gr. Pyrodex pills under 245 gr. Powerbelts. Yeah, I've heard a lot of flack about the Powerbelts, but they seem to work good for me. Shoot acceptable, and knock the snot out of a whitetail. But back to my main point....the recoil with that particular gun and load is all I want. I'm not even gonna consider the 150 max charge, thank you...
