Trapdoor Rifles

Yeah, I’m sort of surprised honestly. The carbine was way more accurate.

Did you use a filler to take up air space?

It includes a sectioned cartridge and other info for the Trapdoor, plus other things from muskets to small bore rifles.

John, just wondering about the sectional views in this article. They show no filler in these views??
This procedure goes against any logic with shooting BP as there should be no air space. Is this sectional view the actual load used or is it missing some sort of filler?

The sectioned cartridges shown are original rounds with nothing added or removed (except half the cartridge). The work was done a specialist from Canada who has done thousands of different small arms cartridges from the most common types to exceptionally rare specimens with only a handful know to exist. His work is truly the standard by which all others are judged, and he did the ones in the article specifically for me.

You can see more of his work, as well as a ton of other info on all type of ammunition at the forum of the International Ammunition Association at:

Yeah I won’t get into the air space thing. As you can tell I don’t give many specifics out when it comes to loads. There’s not much published data and each gun has had its own different wear, fatigues and aging going on so you are really on your own for most of this stuff. I have to say this bullet has far exceeded my expectations. I’m going to load some up for my 1873 colt cavalry revolver and see how they do, I bet they will be fantastic sized properly.
