Well this thread is a little serendipitous! Today I'm ordering replacement nipples for my Pietta Colt 1860 because number 10s are too small and number 11s are too big. So I hot-footed it over to Track of the Wolf, which has AMPCO nipples in stock, but I want to be sure that I'm getting the right thing. I picked out the "Nipple, 6-.75mm metric thread, for replica Remington or Colt revolvers by FAP - Pieta, #11 cap, Ampco bronze". Correct?
And, since we're sort of on the subject, I'd like to replace the original nipple in my 1862 Colt contract Springfield rifle with a new one so that I don't pound the antique one to death. Track of the Wolf gives me too many options. I'm pretty sure that it's a 5/16-24 thread, but I'm not positive. Who wants to help me out?
