Powder charge for Navy Colt with conicals

Niederlander · October 04, 2021, 06:44:54 PM

Gentlemen, I'm going to try authentic conicals in my Uberti Navy Colt. How much powder fits under that an a felt wad? Just need a starting point. I know it's always 22 grains under a round ball.

Check out this youtube channel, he does a lot of work with conicals and is fun to watch.

From what I've been able to find, it looks like about fifteen grains. Should be a good place to start, anyway.

Ah Ha

A question I can answer !!! Okay !!! I don't have a clue

Never shot conicals although another shooting friend has sent me some, haven't shot 'em to date. But, it's really simple. Take the cylinder out of the gun (or not). With a stick that fits the chamber, first measure the conical from base to tip. Mark stick with pencil (or Pen).
Pour some poudre into the chamber until it reaches the bottom of the stick when the stick is held with the mark on the lip of the chamber. Then add just a little more so you can compress it.

Now . . . . and this as really really important . . . . the actual amount of poudre is completely immaterial. Seriously. So long as you get a tad of compression, your gold. Oh, I almost forgot. I suggest 3F.

See !! There it is. Super simple. Shouldn't take more-n-hour to figure out. Easy Peasy.

The military charge was 17 grains powder, no wad, bullets dip lubed in Paraffin wax.

Not rocket science with BP. Put in enough powder so the ball and wad will seat below the level of the front of the cylinder. Weight is irrelevant. Take a dowel and mark it so the mark is at the length of the ball and wad. Keep putting powder into the chamber and inserting the dowel until it is filled to your mark on the dowel.

I'm thinking fifteen with a wad would be a good place to start then. I'll order a 15 grain spout for my flask and adjust from there.

Tother day I completely forgot. For my .36 Navy's, I really like the EPP UG-36 bullet. It weighs in at a whopping 90Gr and has a rebated base to square it up on the chamber mouth. The thing also has an enormous Lube Groove and carries a boat load of lube. Finding the powder charge is exactly the same as my and Pettifogger's above methods.
