Powder
Goex offers a powder called Clean shot.
It produces less fowling and smoke.
It is about twice what regular black powder is but leaves no corosive residue and does the same job.
I'm not positive if they have a priming powder or just one grain size.
I use regular 3F for just about all my guns and 4F to prime. Goex is Potassium nitrate, Sulfer and Charcole. Thats it. The same mix used for 300 years.
If you run a search you can find the phone number and the company is located in Minden, LA.
I'm a black powder nut. Been shootin' it since I was 8.
I like it in stead of any other propellant.
It's dirty, stinky, and quite explosive. Don't ya just love it.
