Well, The Enfield was taken to the range today and WOW! Was it interesting!
We began by using 70 grains of real black powder. At 50 yards the first volley of 6 rounds were in a 6-inch group, aprox. five inches above the bull’s-eye. Not too bad for open sights.
Then it got real weird…
We opened a brand new container of one of those black powder substitutes. We wanted to compare the pattern to good old black powder. A huge reduction in recoil was noticed, and the pattern opened up. It opened WAY UP!…
Of the next six shots fired, only two holes could be found in the 4-FOOT by 4-FOOT piece of cardboard we had our bull’s-eye centered on. The two holes we 3 foot apart, and both of the holes were misshapen. One was oblong and the other was the perfect profile of the minnie ball… Obviously the bullets tumbling as they were going down range. But what caused this? And where did the other four rounds go?
I switched back to the real black powder and the group tightened right back up. The recoil also returned too its previous level.
I had also brought my Pedersoli 12gauge side-by-side muzzle-loading shotgun to the range today, so we preformed a little test… I loaded it just as I normally do, but I used the new powder. I then fired it towards the target… Once again there was a noticeable drop in recoil, and this time we could see a burning wad fly about 10 yards down the range. I had never seen in flight, or even found on the ground, a wad that had been fired form this gun.
After much thought, here is my hypothesis: The new black powder substitute was defective. It was extremely slow burning. This would account for the reduction in recoil, and it would explain why I could see the wad after it had been left the shotgun barrel… The powder that had been packed against it, was stuck to it, and was still burning as it went down the range.
As for the 4 missing .58 caliber minnie balls… I believe that the hollow base of the bullet was filled with the defective slow-burning powder. This powder was compressed into the hollow base of the bullet when the ball was packed onto the powder by the ramrod during the loading process. When the musket was fired, the cone shaped charge of powder in the base of the bullet was still burning after it had left the end of the barrel. This gave the minnie balls the characteristics of an unguided, un-stabilized, missile. And they propelled themselves at least the two feet required to completely miss the target.
