I tried two new x-spear-i-mints.
Cartridge, Shot, ML, 12 ga. Mark I*
Same as the mark I in my prior post, except that ;
- Made the tube on a tapered white board marker
- Squished a cushion wad so it would push down about 1 1/4 inch
- added a measure of shot
- fitted an overshot card over the shot
-`slit the remaining paper into six petals, fold and glue (Or glue & fold?)
- Lube the paper tube. This time I tried Lyman BP Gold
- Measure in the powder into the other end, fold.`
The difference was putting the overshot card inside the paper tube. I thought it would not be as likely to fall off. The trick is to get the tube just right. If it is too big around it won't slip in properly. It HAS to slip in freely, up to the overshot card, but not too thin or the overshot wad won't fit right. Again no problems, and it didn't slip forward when the other barrel was fired repeatedly.
Cartridge, Ball, ML 12 ga. Mark II
I got this idea from an article in The RIFLEMAN, about the CSA powder and ammunition article (last year, I think). The problem is that a paper wrapped ball is not likely to fit well enough for accuracy. The CSA used English cartridges that were different than the wrapped paper tube that I described above. It was a cardboard tube, with the bullet at one end, pointed towards the middle. The powder was on top, and sealed. to use, open the powder end, and pour. Then place the bullet end over the muzzle, and ram it down through the cartridge. Discard the cartridge, cap, level, and fire.
For my tube I used 12 ga. cartridge bodies, with the head and crimp cut off. Use paper, or the plastic shells made from tubing. (A-A's won't work, or any moulded shell like it).
- Ram a ball with a lubed patch down through the tube.
- Ram an overshot card, or one punched from paper milk carton, on top to keep the powder from the patch lube.
- Measure in the powder.
- Finally an overshot card to seal the top. I ran a piece of string under this card so it can be lifted out to free the powder.
To use; Lift out the top overshot (over powder?) wad, and dump the powder in the barrel. Place the tube over the muzzle and ram the patched ball through it, drive home and tamp. Cap, level, aim, and fire.
This one is really simple and easy to use. It doesn't seem to work with shot, as the shot column seems to press outward, making it impossible to ram, but for ball or minie bullet it's great. I tried both paper shot shell bodies, and plastic. Paper for smoothbore and tradegun matches, and plastic for game, and practise.
For a 12 ga., or any standard bore, use existing shotshell bodies. For ML Rifles? I just measured a piece of copper plumbing, and it came out to about .54. Maybe that will do for my .54 Mortimer Flinter? I'll have to figure out how to make durable tubes for other calibres.
