I have a two banded Parker-Hale Enfield, English proofed, and used it for NSSA competition.
As others have noted, use flourescent Day-Glo Orange paint or white paint for the front sight to make it stand out.
Use Silver solder in the rear-sight and a fine jeweler's file with a knife edge to cut the rear "V" in the silver solder. Be carefull where you put the "V". You may have to accomodate to the left or right of center, and the depth of the groove will effect your elevation.
I found the Old-Style Minnie works best in mine.
Also, check out the diameter of the miniball you use. They vary from .577 to .578, etc. Each barrel is slightly different and each gun performs best with the right caliber mini-ball. I'd suggest buying a few bags of commercial mini-balls of different sizes, test each of them from a bench, using the same load, and buy a mold for the size that produces the best group at the range you normally shoot.
Then work up a load for that range. You'll find that the groups get tighter as you reach the best load for that gun, then widen up again. For hunting, your not after the same accuracy as target shooting. Also, the type of lube you use can effect the performance of the gun, and the type of lubricant you use in say, warm weather, should be different than the type you use in colder weather. The colder weather lub should be moister.
I used melted crisco in the hollow base. Then I waited until the crisco solidified and dipped the base and the lub rings on the sides of the ball into a melted mixture of beeswax and commercial lubricant. I used more beeswax in summer and more commercial stuff in the mix in the winter.
When you cast your own balls, discard any, of course, that have ANY irregualrities in them, especially if there is any flaw in the skirt, as the pressure of the discharge can blow away the skirt as the ball exits the barrel, causing a "flyer".
One more thing. Mine came out of the box with an incredible trigger pull. I had it reduced to what the NSSA minimum was - either 2 1/2 or 3 lbs - I can't remember.
My most accurate load was about 45 grains of FFF for 50 yards using a 6 o'clock hold. But again, accuracy is sacrificed in hunting to killing power. I believe the official Army service charge was 60 or 70 grains of FF - again I can't remember exactly.
You might want to invest in some plastic shotgun gizmos. We would put the pre-measured charge of black powder into the plastic shot gun gizmos and then stuff the ball in hollow side out. After you put in the liquid crisco, dip the base of the resultant cartridge into the lube and make sure the lube covers the point where the ball and platic meet. It will seal the black powder in. Such cartriges can last a long time.
When its time to load, pull out a cartridge, grasp the ball in your teeth, pull it out, pour the charge in the barrel, place the ball in, ram home, raise, cap, aim and fire.
Like Colonel Shaw said in "Glory" a good man can get off three aimed shots a minute like this.
Also, make a mark on the barrel with a punch at the point where the tang screw slots line up when they are tightened up right. Do the same on the stock for the two lock-bolt heads. Make sure, if you pull the piece apart for cleaning, that you never over- or under- tighten the lockplate or tang screws when you reassemble, as it will change your point of impact when you shoot the thing.
My Enfield is one of the most accurate pieces I own. It shoots better than I do, and I'd trust my life on it.
Good hunting.
