Loaded ammo has quite a taper compared to these inserts..The loaded 7.62x 25 is very sloppy fit in the chamber... I didnt have machinist dye so I used soot
but then didn't you say
I coated the adapter with valve grind compound and spun it in and out of the barrel until it went easy
so you basically reamed out the chamber so it would be sloppy after 8 rounds being drilled into it with valve grind compound... stock ammo is like sloppy seconds
