Ruger Old Army
If JT's Kroil or Sea Foam Deep Creep and an 'easy out' does not work. I think ROA nipple threads are 12x28. Drill with #15 drill bit .1800 in. Then tap with 12x28 tap. Go gently with drill bits, 'easy outs' and taps, they are hardened tool steal and will multiply minutes to hours if broken off in a hole. 50/50 ATF and STP is better than any over the counter tapping fluid. Good luck
