Black Powder Granulations

[44MAG#1]

Tried to delete post but couldn't.

I am of the same thought as your friend.

Would be interesting to find a known can from that era and screen it comparing to todays and the screening. It would have to be from a can or keg since coming from loaded cartridges its compressed and dug out

[SSGOldfart]

Well the southern troops used smaller granules then the Northern troops it was due to trying to make it go further.The South also used a lot of river willow to make their own powder.

My sentence below paraphrases the point made in the above link.

If your firearm is producing less than the historical velocity you expected with the historically correct quantity of powder then change to the next finer granulation and re-chrono the load.
Also moving to a higher quality of powder plus the finer granulation will put your MV up where it will be historically correct.

I have some 3fg Old Eynsford BP on order so I can test this in my own 45 Colt New Vaquero.

I tried that in my short barrel Colt. It's pretty dramatic and plenty powerful, and I went back to 2f just to calm it down a bit. That old 45 is pretty impressive when it's loaded like it's meant to be.

I know a lot of folks use FF in these cartridge rifles but let me say this without meaning to ruffle any feathers. I’ve shot muzzleloading rifles ( not cartridge rifles ) and smoothbores all my life with tack driving accuracy using FFF Goex. My 50 cal. will wear out the bottom of a dixie cup at 50 yrds. Does anyone use FFF in their cartridge rifle. I’d love to use it in my 45-70 cause I have 4 lbs. of the stuff.

I use 2F and 3F OE and Swiss in my .45-90, .44-75 Ballard and the .44-100 Rem Straight.

FFF will work fine in your 45/70 -----if its a modern build rifle - FFF certainly is gonna generate more pressure than FF - so if its an 1800's roller or trapdoor maybe give that old steel some extra respect.

I shoot FFFg in my '86 chiappa and my sharps (45/70's) and in muzzies up to 50 - got a 54ml and an 1876 uberti that get FFg -

Once you start playin 4lbs of powder will disappear quicker than ya thought!

After my first cylinder of 44WCF 2F loads in my 1858 conversion all I could think of was ...."why, why would anyone think we need a 44 Magnum?" An impressive fire breathing dragon for sure.

[Nobade]

Exactly.

I won some 2F Old Eynsford as a door prise at the last Lodi match. I thought I would load it for my daughter's rifle for the upcoming Quigley and when I opened it up I was surprised at how fine it was. It looked like a mix of 3F and 4Fand the granulation was not very uniform so I went back and loaded with my normal 1- 1/2 Swiss. There's quite a difference between 1 1/2 Swiss and 2F Olde Eynsford granulation with the Swiss being more course. I think each company has their own idea of what the size should be when it comes to labeling their powders.

The label on my canisters of Olde Eynsford say “Royal Blend” so I believe that this powder is a blend of powders from different sieve screen sizes. As you and I observed OE granules size is not uniform as would be culled from a single sieve screen size.

[Huvius]

I use Olde Eynsford 1-1/2F and 2F and the 2F is much finer than the 1-1/2.
So much so that I haven't even tried it in any of my big bottle neck cases.

1-1/2 on the left, 2F on the right:




The original Eley 450/400 cartridge I dismantled had bigger granules than the 1-1/2F OE eventhough it was compressed into the case. It all picked out with very even granulation and very little fines in the case.

[country gent]

I believe Buffalo arms in their powder section has the screen sizes for the various powders not only by granulation but maker also. This might help some

swiss black powder only.

1-1/2f for all bpcr/tr cartridge rifles, 3f down the tube and in the pan for all flintlock long guns.

when i had cap'n'ball pistols, 3f only.
