Measure Question

I do not have the proper power measure for my ROA 44 and do not have the time to order one. No one in my area has any. We are leaving tomorrow for nothern Michigan, i would like to shoot this gun while i'm up there.
I using Triple Seven and Hornady lead balls.

I was told that and .38 spl case holds thrity grains.
Is this true? and would this load be okay?

Thirty grains of T7 is a fairly stout load for most guns!

I don't think it would ever come close to hurting a ROA though.

I think I'd go with a .38 Long Colt or 9mm full of it though myself. No need in getting a sore wrist.

Are you driving or flying? If driving, it is likely that there is some outdoor store along side the interstate that you'll be able to pick up a measure at while the rest of your party is ordering your meal in a restaurant. But then, I don't know Michigan- that is just a guess.

A .38 special case holds, by volume, 23 grains of Goex fffg black powder.

Twenty three grains of 777 would be a good load for your pistol, you could "heap it up" a bit and get a 25 grain charge, perfect.

Thanks for the advise. I wanted to make sure that I was using enough and not too much. I will be looking for stores along the way. There is one that I know of that might have the powder measure. If not I'll use the 38's and try a .357 case.

Thanks again.

Someone posted this:

Quote:
an empty (fired that is) 7.62X39 case (AK OR SKS) is a good powder measure for the .44 BP revolver. when filled with 3F about 28grs 3F and place a felt atop the powder. then greased slug/ball.
Loading 28 grains volume of 777 as described above would be equal to loading ~32 grains of BP due to 777's 15% velocity differential.

As Ronald Reagan always said, "Well...."

If you are driving there is a Bass Pro Shop in Detroit.

What route are you taking? There are plenty of places you can get a powder measure. Perhaps I can help.

Oh my goodness this does NOT sound prudent at ALL

Start with a 9mm then go 38 special-

Heck, I could find a powder measure faster than I could locate a 38 long.

You're correct, I didn't check to verify the volume of the empty 7.62 X 39 case.

According to Wikipedia:

Quote:
The 7.62x39mm has 2.31 ml (35.6 grains H2O) cartridge case capacity.

http://en.wikipedia.org/wiki/7.62x39
And 2.31 ml equals 2.31 cc's or 35 grains of powder, very close to the same volume as it's H2O capacity in grains.

And 35 grains of 777 would equal 40 grains of black powder by volume, which is certainly not ~32 grains which I quoted.

Maybe the original poster was only filling up to the beginning of the case neck which is 38.7mm lower from the top rim of the empty 7.62 X 39 cartridge case.
Thanks for the being alert and catching my mistake.
Quote:

Apparently the empty 9mm case holds 13 grains of 777 by volume which is equivalent to 15 grains of BP.

Quote:
The 9x19mm Parabellum has 0.86 ml (13.3 grains H2O) cartridge case capacity.

40 grains of bp is about all a ROA chamber will hold and still have enough room to seat a round ball. This will get you about 1000 fps with Goex 3f.
I have tried 40 grains of Goex 4f and got 1150 fps out of it.

You won't blow up a ROA with black powder or its replacements. The gun was designed to be safe with as much black powder as the chambers will hold. The reason for measuring is shot to shot consistancy.

Mykeal, we are coming up I75 to US23 then 65 to river road. I think that the gun shop at Bunnuan Town may have it or the Wal-mart in Tawas. If you know of any others along the way please let me know.

Thanks

That's probably close if not ideal for maximum accuracy. The only problem is that the ram is not long enough to compress the powder. After putting in the powder, top it off with some sort of filler, cornmeal, Cream of Wheat, and then seat the ball.
A .38 special case full of powder and then a 9mm case full of filler is probably good. I have used Wonder Wads as filler but that gets expensive.

Maybe. I think you'll do better at the Tawas Do It Best Hardware next to Neiman's grocery store. Wal-Mart here is not good on bp supplies even in muzzleloader season, and Bunyan Town is really hit and miss. I don't trade with them any more.

Frank's in Linwood (on M-13) usually has a good stock but prices are full retail.

Best bet will be the Tawas Hardware, however.
