12g BLACK POWDER

[Peter Dunkley]

Another of my bp boxes went this morning so lots of people are getting into it.

Hi would you mind sharing your standard black powder load formula,

I put together BP clay loads for my 20g SxS and use the on the grouse set up.
Way too much fun.
I have found that an equal volume 21g load does not pattern as well as the square 24g load.
This is annoying because i can get a star crimp on the 21g but need to roll the 24g.
(I like to use a length of wad that exceeds the diameter of the bore).

1 dram of black to each half ounce of shot is a fairly standard rule of thumb.

This may help. Obviously, safe reloading is the responsibility of the individual.

Scroll down the pages to see the loads.

I note your point and thanks for the link. I had not seen that one.
The data is aimed at muzzle loading which I do not do. I was asking about cartridge loads but the data seem very similar.

I think the only difference between the loads for muzzleloaders and cartridge loads would be the resistance caused by the crimp or rolled turnover. Perhaps reducing the load by 10% would compensate for this?

For 20g cartridge clay loads I use the 4.0cc Lee dipper.
This gives me 24g of 7.5 lead shot and I use an equal volume of FFFG.
An exceedingly pleasant load.
