All these little pistols need custom ammo - I see Bill Wilson even produces special ammo for the 3" 1911s. NAA went that route with the NAA 25 and 32 (bottle neck cartridges). There are just too many variables in ammo and the micro pistols seem to find them.
Experimenting with different ammos and FTF, or FTE, become very frustrating. The seecamp was built around the old Winchester Silvertips and ran like a swiss watch - then Silvertips changed. I have a broomhandle mauser and runs like a sewing machine on Finochhi, but won't cycle with Privi Partizan
Larry Seecamp and Rorhbaughs are perfectionists, so this will be interesting.
