Rifle Single Shot I THINK I Can Make This

Sorry about the tardy response. Only excuse is "It's Springtime in Alaska!"

Re bore/chamber size:
Nah. I checked, (mic'd), before test-firing.

I think the 'purple' blanks are not for using in firearm. By that I mean that I know they are made for "nail guns", but they are really not intended for use in firearms. Why would you need a 'muscular' blank?

They MAY 'work' in the "Flobert" I'm making. (Yes, I'm still making that.) Given the potential cases I intend to use, maybe the extra case capacity will render the purple blanks useful.

I THINK I'm going to make my own .25-20 cases for the purpose of using the nail-gun blanks. The combination of larger case capacity, completely enclosing the blank in a close-fitting "chamber" within the fabricated .25-20 case MAY allow them to be used. One issue remaining is "headspace" - the fit of the breechblock to the breech. The "Flobert's" design does not ensure a tight headspace. The greater the headspace, the greater the chance that the purple blanks won't be able to be used. Just too powerful. Furthermore, the strength of the purple blanks may obviate their use because they propel the bullet faster than I want (subsonic). Time will tell.
