10 gauge RCC brass

[Harry Collins]

My turned brass hulls took 209 primers. I loaded them on a MEC Jr with SP-10 wads then hot glued the over shot card. I was using Sherman Bell data with IMR 7625. That powder is unavailable so whatever a good low pressure powder you want will work.

Harry, if the brass hulls are in otherwise good condition see if you can find a 12 gauge sizer die. Possibly from a cowboy die set Lyman or RCBS. I found mine in a box on a gun show table many years ago. Solid brass cylinder with a rim cut. Lube the hull and drive in with a raw hard mallet and push out with a dowel. i have one hammer gun dedicated to these shells and even so they benefit from a resizing every now and then. They last a very long time and may need to be annealed occasionally. When the mouths start to split the can be trimmed and continue in use. I only use black powder with these loads and the perform very well.

I dont know how this applies to shotshells but ive read with blackpowder rifle cartridges you want a good gas seal to keep fouling from blowing back in the action as cleaning the bore is easier then taking the action apart after every shoot . Is that a problem when reloading black powder in brass shotgun cases ?

What brand of bp do you use ? seems alot of guys really like the swiss stuff .

I kind of want to try fiber wads , Ive read that brass hulls usually have less pressure compared to modern plastic hulls as they have no base wad .

I seen a bluedot load for the 10 gauge it was 8500 psi , I wonder in a brass hull and with fiber wads what the psi would drop to . I suppose I could load those and have them pressure tested .
