Musket caps?

[deaddog]

Been using cci musket caps and T.C. musket nipples. Those are the ones that fall off without a pinch. Hey robodad, seems like back pressure thru the nipple maybe. does it do the same no matter what you load, smaller charge or looser fitting bullet?

[robodad]

The nipple I use came with the ML so I don't know which brand it is but the caps are CCI and Yeah deaddog, I think it is too much back pressure, I wonder if it is because of the smaller granulation of the FFFg 777 ?? I have tried the pyrodex in FFg and don't remember having this issue, I wonder if T7's FFg would do the same thing.

Does it really make that big of a difference in a rifle vs pistol using the FFFg instead of FFg, my shoulder says hell yeah that T7 has a real crack to it vs the pyrodex from what I have noticed but what about the granulation size ??

Thoughts ??

I think I remember something about t7 being 10% stronger and I would think droping to ffg might make a differance.

It's 15%. So an 85 grain charge of Triple Seven would be equivalent to a 100 grain charge of black powder.

From Hodgdon's site:

Triple Seven is a high energy product designed to provide the muzzleloading hunter with higher velocities when used in the same VOLUME as blackpowder. To duplicate a blackpowder load velocity using Triple Seven, you must decrease the powder charge by 15%.

and 100 grains of T7 = 117.6 grains of black powder. When you think about the charge differance. its huge. Shooting 150 grains of T7 is like 176.5 grains black powder.
