Powder Measure for Shot?

[GregC]

Is there a rule of thumb for using a powder measure to weigh shot? Some sort of equivalency? The TC owners manual says that 60 grains = 7/8 oz shot. How about 1oz, .75oz etc?

Thanks

I have found this to be helpful and it may have been already displayed by someone else, I have not done a search to see. Maybe it will answer you questions, I know it gave me a few pointers. blackpowder shotgun basics :m2c:

Thanks, He-Bear. Great info and great timing; I just got a SxS percussion 12 guage.

Check my thread "SxS Percussion 12 Guage" on this board. Rebel gave me some good info on calculating shot weight by volume. I'm sorry I don't know how to link that thread for you.

On second thought I can quote Rebels post for you:

I have a Navy Arms double barrel. They do have a manual for there shotguns. I used the info in it amd in the T/C manual as well as from things i read in muzzleloader magazines. If you start with 70 grs of 3f Black powder or the same volume of Pyrodex RS, an overpowder wad, half a lubed fiber cushion wad, 1 0z (just use the 70gr setting on your powder measurer to get 1 oz) of shot, and an overshot card wad. You can also use plastic shot cups to tighten up the pattern. They list 102 gr. (3 3/4drams)of powder and 1 1/4 oz of shot as a maximum load. I normally use 90-95 grs of Pyrodex RS and 1 1/4 oz of shot for most of my hunting. My shotgun has cylinder bore barrels. Mine also shoots well with .690 rd. balls.

I use an old powder/shot dipper. It is 5/8" ID and adjustable in depth from .950" to 1.7". It is marked for ounces of shot and drams of powder, from 1oz.=2 1/2 drams, up to 2 1/4 oz=4 3/4 drams.
It's easy enough to calculate proportions from that, 2 1/2 drams would be 68 grains per ounce of shot, say 70 gr. close enough.
Volume measures are never exactly as marked and it depends on the shape of the measure. A long, narrow measure such as the common adjustable powder measure will not throw the same proportion of powder to shot as would a short fat measure like my dipper.
Confusing enough? Well for all practical purposes, just say 70gr=1oz and 90gr=1 1/4oz and as Jeremiah Johnson told his bride, "that is all you need to know." :haha: :haha:

Well if all that everyone has said is not enough information here is some more. This is about dram to grain conversion and other stuff, maybe it will help or confuse you I do not know.
dram to grain conversion etc.. :m2c:

I use the same setting for shot as I do powder, this make for less equiptment to carry afield...
