I have found that there are two definitions in use for “inside lubricated bullet”. One definition refers to the location of the grease grooves, these being hidden by the case when loaded. The converse of this is the outside lubricated bullet where the grease grooves are visible when the bullet is loaded into the cartridge case. Then there is also the more specific use of the term “inside lubricated bullet” which refers to a patented bullet design whereby the grease is forced from the hollow of the bullet through small holes. So when I refer to a cartridge loaded with a bullet having hidden grease grooves as “inside lubricated”, am I wrong? Is there another term for this type of bullet? How do other people use the term “inside lubricated bullet”? This may seem pedantic and trivial but and it has been bugging me for quite sometime and I would like to be clear with my cartridge descriptions. I would like to hear what other people think. Thank you.
