Adice you ask:
I bought my screwdriver set from MIdway. It has about 20 different sizes flat head bits. I dont know the brand offhand. Anything they sell will be fine. The set also has little punches for those pins.
Before you try to remove the breech plug dont forget to remove the touchhole liner. I clamped the barrel in a large vice with a thin peice of leather to pad it and used a very large about 18" crescent to turn the plug. There might be a better way but that is what I did.
Regarding the drilling. Find some one with a drill press and it will take him less than a minute to drill it out. Lacking a drill press clamp it in the vice and I would go for it with a hand drill on low speed. I think it will work leastways if it doesnt I dont think you will damage anything. I drilled mine to 5/16 (31cal). There seems to be some debate here on what diameter is best. If I was doing it again I would think hard about drilling it out to 7/16 44cal so the cleaning jag will reach the bottom of the barrel.
After you drill the plug shorten the touchhole. The professional way to do this would be on a lathe. Lacking that use a pair of pliers to hold it up to a grinder and remove a couple threads.
When you put it back together slather up the plug with some zinc antiseize so the next time is easier.
This took me about an hour one afternoon after spending half the day with a ball puller fighting with it. I was pretty aggresive about fixing a gun I was about to throw away.
Go for it. "Failure is not an option". "LIVESTRONG" and all that
