Looking for black powder low pressure load data for my 10 gauge

[Tripplebeards]

Rolled 4 to try yesterday with #5 shot and 100 grains of FG. I cut the hills a little longer this time around. The chamber is 2 7/8” and I cut the hulls to 2 3/4” before roll crimping. Think I’ll be cutting them this long or longer to keep some extra hull length so,if, and when, I need to shorten after shooting I have room to play with.



Sealed and numbered…

Tested the above loads the other day….






Here are my targets from a few days ago. I tested 100 grains of FG in a Winchester hull. I loaded with a 1/4” nitro wad and 1 5/8oz of #5’s. It didn’t group as tight at 25 yards than my #6 load but IT DID have more hits at 40 yards than my test with #6 nickel plated shot. That was kind of confusing to me. It didn’t pattern any better than the RST load at 25 yards but patterned better than any load I’ve tried at 40 yards to date. At fifty yards I only had 3 hits VS with the #6’s.

I then tested all brass hulls with the same exact load but added a 3/4” fiber cushion was over the 1/4” nitro wad. The groups were poor compared to the plastic hull loads.

I have to get back to work unload development for this gun! I have missed two Toms with it since my last post and basically hung it up to pasture. The first one I believe I pulled the wrong trigger in the spreader barrel was the issue and blew the shot out to the point I didn’t connect with the bird. The following year I took a shot at two Jake’s at probably 15 to 20 yards and they just stood there and looked at me. I know I had some oil or something in the barrel and I could tell it sounded weird when I pulled the trigger like a double kaboom, so maybe it was old powder or contamination or something weird happened. The way the birds just stood there and stared at me so I have no idea what happened. I don’t know if I pulled the wrong trigger again and shot the spreader barrel or something else weird happened. I doubt I forgot to pour in shot….lol. Figured that maybe I had a lot of oil in the barrel and maybe it did ignited when I shot because I could see some flames go sideways out my breach and barrel lock up area… it was just the flames coming out the end of my gun like in the pictures I’ve posted and I thought it was close-up but something tells me that the oil I used to clean the barrel and keep it lubed probably ignited when I shot and maybe veered off or maybe I flinched a little when there was a delayed firing??? I never miss birds and I missed two in a row, so it was enough to make me mad and hang it up.
