Anyone ever used real smokeless powder in a muzzleloader???

[GeneCockrell]

I am wondering if anyone has used real smokeless powder (not the "black powder replica" smokeless) in a muzzleloader.
I know you always see advisories to not do this and that smokeless CANNOT be measured on a volume for volume basis with BP but I also know that the 45/70 is a 45 caliber rifle that was originally loaded (for the trapdoor springfield) with 70 grains of blackpowder in a straightwalled case and that 70 gr of BP will pretty much fill a 45/70 case.

Now, there is plenty of reloading info for the 45/70.

But consider, in a 45 cal muzzleloader you have a straight chamber at the breech end of the barrel.

Perhaps due to the charge being compacted (it wouldn't be in the 45/70) you may have higher pressure and should use instead data for something like the 45 long colt.

Any input or ideas?

(I'd try this but I sold my 45 a long time ago)

as near as I have been able to figure smokeless powder is roughly eight times more powerful than blackpowder by volume..as near as I have been able to find out modern smokeless powder is actually Nitroglycerin stabilized in charcoal but I would not swear to that in a court of law

IT IS DANGEROUS TO USE SMOKELESS POWDER IN A MUZZLELOADER!!!!!!!!!!!!!!!!!!!

exception, Savage has one made for smokeless, with a narrow powder selection.

"YOU DON'T USE SMOKLESS POWDER IN A BLACK POWDER GUN EVER!"

"Advisories are for people who can read, and only work if a person has common sense." You don't use smokeless in a Black Powder Gun, Period. It can come apart, if not the first time, it will eventually. Not a pretty sight.

You better hope that 45/70 case is full and you press that bullet down to compress it. If not you use a filler like cornmeal or oat meal. Example: 60gr BP and 10gr cornmeal on top compress the load with the bullet.

If you don't lose facial parts the first time you drop the hammer you'll be extremely lucky.

its apples and oranges

the gases escapeing out of the nipple could destroy the hammer
smokeless powder is NOT made to be packed.
BP Has to be packed to function properly of there is air space in the chamber with BP
It is a Bad thing.
smokeless it is common to not have the cartrige full up
the amount of energy in Smokless powder is incredible compared to BP
getting the invention of gun powder to do what it does is one of the greatest technological break throughs that Humans have ever made.
To discover and find a use for an explosive powder
a controllable explosive
We humans did that
over 2 thousand years ago.

Pretty cool huh?

Dennis, the packing of BP is right. I once didn't seat a ball properly, and it hurts when you shoot.

Guys,
I once touched off a revolver that had been loaded with smokeless instead of BP without me knowing it. I'm just glad no one got hurt, but the person who filled that flask with smokeless got a good beating for their stupidity/irresponsibility. From my experiance, i'd recommend paying attantion to that warning most of them have to use BP only.

Back in my younger and more carefree days (in the years B.P.- Before Pyrodex) we used to mix 95% FFFg and 5% Bullseye pistol powder (by volume) in muzzleloading rifles. Supposedly the BE kept the fouling to a minimum. Nothing ever blew up, but !!!! we were clueless in those days.

[Bountyhunter]

Now that that has been answered, if you get to wonderin about it again, just take your rifle down and get your refund. That way you wont have one to be tempted.

You got 19,000 pressure in a .45-70 Trapdoor Springfield load.

You got 23,000 pressure in a .45 ACP Imagine what you would have if you had more than 5 grains of powder.

DONT DO IT.

[FROSTY]

Stick with black powder, by all means, my friend...Smokeless powder in a muzzleloader=hand grenade :insane: If you live to tell about it you'd realize that black powder is meant for muzzleloaders, and is by no means a second rate propelant... :jaw:

like the others said, don't try to kill yourself, unless you have a
Smokeless cylinder for muzzle-loading revolver

Is fairly new (august 2005). I ran accross it when I was looking
for some colt patents the other day. Don't know if anyone makes them commercially.

Anytime i see a warning in big letters like DO NOT USE SMOKELESS POWDER I normaly listen to it.Normaly.
