You also said that the Starline brass had[b] large rifle holes and the Norma had the small rifle holes. I can't say that I knew there was a designated small rifle hole and a large rifle hole. Is this a SAAMI thing ? I just assumed each brass maker punched or drilled a hole they thought would work the best for their product. [/b]

Now how could it be a SAMMI thing?

Small primer pocket rifle and pistol cases use a smaller flash hole size of .074" - .078"

European CIP brass use 1.6mm - 1.7mm flash holes.

Original spec on 6 PPC which we all know is the most inaccurate round out there is .0625

Seems that smaller is better.
