Yes and no, black powder is limited in pressure when you use a traditional primer because of the fluid dynamics of how your powder burns when you're burning powder from the bottom, up.
What I've found is if you increase the width of your case, you can burn the same amount of powder faster, by increasing the surface area od your priming detonation. Think boiling a pan of water, vs a long pot. Same amount of heat, but the more you can distrivute it, the better.
Taking that to the next step is electric priming which Remington once upon a time, tried out. All they did was plug a copper puck into the primer port of a traditional case and called it a day. What Ive done is use a full rod inserted into the body of my case to increase the surface area my black powder gets to the primer. This causes more black powder to detonate immediate, causing that pressure spike necessary to get more velocity.

Then you need to invest in a drill press. If you can afford a 3D printer, a drill press is much less expensive and with the right tooling, can do quite a bit. A used drill press can be had fairly cheap, the older, the better. Old machines just work, and can do primitive machining if you've got the tooling.
