Can you 777 powder in a musket cap in-line? I have a older Knight LK93(musket cap) and just bought a new MDM Quicshooter(209) from Cabelas. I wanted to use the same powder,2 pellets in LK93, and 3 pellets in MDM, but wasn't sure if a musket cap would ignite 2 777 pellets in the LK93. It seems it would be alot cheaper to use 777 powder(cost per shot).Although I like the convenience of being able to just drop 2 or 3 pellets. Whats the the other advantages of Pellets? I heard they are less prone to absorb moisture.

Loose 777 will work fine with musket or #11 Caps. Hodgdon only recommends using 209 primers with the pellets - and it's probably best to heed that recommendation. I had a few problems using #11s with Pyro pellets and they have that coating of black powder on them to improve ignition while the 777 pellets do not.

Loose Powder IS much cheaper to shoot and it allows you to customize your loads down to 5gr increments while pellets can only give you 10gr differences at best. And to be honest, with the use of speedloaders, you can load loose powder just as fast as pellets. Pellets MIGHT be a little less prone to picking up moisture - but that advantage is probably over-ridden by the fact that they can also crumble some too in storage........making your loads more inconsistent.

If you use loose 777, remember it is more powerful than the pellets...................so to get a similiar result as your 100gr pellet load, you need to start working up from 80gr of loose 777 in 5gr increments. And 120gr of loose 777 is to be considered a magnum load - don't exceed that.

I use musket caps in my remington. I have shot Pyrodex and Cleanshot pellets this way and had no problems with it. I would think 777 would be about the same, but they do suggest 209's instead. If you were to get a missfire at the most inopertune time I wouldn't try and blame them.

Mark is right, loose powder is better anyway. Pellets are just more convenient is all. Of course they are more expensive as well, and you can't tailor your load for accuracy. And with 777 the powder is faster when loose. Two 50 grn pellets of 777 will be the equal of 100 grns of pyrodex pellets. However when shot loose 777 is hotter for the same volume compared to pyrodex. And cleanshot or pioneer as it is called now is even weaker than pyrodex.

I use loose 777 with musket caps and it works great, good luck with whatever you try.
