  1. Try a pump action shotgun with black powder and some sort of .50, like either a Desert Eagle or a .50 GI Glock. Big bore stuff is gonna work better with black powder is my estimation.

  2. I feel like there’s a way to modify a gun to handle the powder, like a lot of thick grease to mitigate the buildup of soot and increasing the chamber pressure with a suppressor to help it cycle.

  3. Scott, I have been missing in action since last November 5th sorry. Went into the hospital for some blood work and upper GI supposed to go home on the morning of the 9th..being wheeled out of my room I coded blue. I don't remember any of that day. Nurse Monica did hands on CPR , her 1st time and got the crash team there ..my wife was there and saw it all.
    Two broken ribs and a cracked sternum and two defibrillator zaps for the next two code blues all this in under 3 hours. So clinically dead three times in one day. Thank God I was at the hospital when this happened.

    Now back to you Scott…lighter projectile and try using proper it burns cleaner..
    You can also try mixing some flash powder with it..use a remote ignition pleasestay safe.

  4. Some black powder burns cleaner than others and also, grain size, as 2x, 3x or 4x and amount of time in the barrel. I think semi autos if designed for bp, could do way better, but new powders were a game changer, for sure!

  5. Sometimes chronographs pick up the unburned blackpowder granules instead of the bullet. Caldwell recommends you shoot muzzle loaders 30 feet away from the chronograph so it picks up the bullet instead.

  6. I wonder how something open bolt would do with black powder. I'd imagine a mac 10 in 45 would chew right through the grime no problem. Maybe even stopping by the hardware store and swapping out recoil springs to something really light would help

  7. Recoil operated actions like the Maxim machine gun and a lot of the Browning designs, including the 1911, will work with blackpowder for so many rounds. Blackpowder was still commonly used in shotgun shells and .22's for decades after smokeless became common enough. I'm completely surprised the AR-15 in .223 functioned at all with the low pressure of blackpowder. If you're using an AR-15 built to Eugene Stoner's specifications, the bolt and bolt carrier will be chrome inside and out, the chamber and bore will be chrome plated, and the gas tube will be stainless. The upper being anodized, hardened aluminum, the upper should clean up well with a lot of water submersion, followed by some CLP after it's dried.

    One thing you really have to watch for is mixing blackpowder or BP fouling with petroleum based solvents and oils. Blackpowder is made of charcoal (carbon), potassium nitrate (a salt), and sulphur (the oxidizer). Tar and asphalt are made of charcoal, crude oil, and sulphur. If you mix oil with BP or BP fouling, you might end up with deposits of asphalt in your barrel or action. The potassium nitrate and other salts left behind as fouling are very hygroscopic, they absorb moisture from the air which leads to rust when the water and air mix with the iron in the steel of a gun, even stainless will corrode.

    Revolvers, bolt actions, and lever actions work fine with blackpowder, but after so many rounds, you need to pour water in the action to loosen it up. After combat engagements, cavalry soldiers wound come into their camp where there was a pot full of boiling water with ash mixed in. They would dip their pistols into the pot short of the grip and swirl them around a few times and then wipe off anything they missed, dry them, oil them and reload them. Back in the day, they used sperm whale oil, aka "sweet oil", which was also used in their lamps and lanterns. It wasn't petroleum based, so it didn't react negatively to the fouling.

    The Germans used Ballistol during WW1 and WW2 because they might end up using blackpowder cartridges and needed an oil that wouldn't react badly. Artillery still uses blackpowder which is why one of the contract requirements for CLP was to be non-reactive with blackpowder fouling.

    The US Army asked Browning to design a cartridge that replicated the old SAA load, a 200 grain bullet going about 800 fps, so he designed the .45 ACP which used a 200 grain bullet going about 800 fps with a smokeless powder load. Then the Army asked him to bump it up to 230 grains.

    Blackpowder also likes to use soft lead bullets, not copper jacketed or plated or hard lead bullets. Soft lead bullets have less friction and get pushed out the bore easier, even if it's a couple thousandth of an inch larger in diameter (.454 vs .452 for a copper .45 bullet).
