Small primer brass in 308 and 6.5

[Bubba Yugga]

Any reason not to drill out the small flash holes?

Why not use a small depriming pin on some & drill out some, say 10 of each & run a side by side test to see which is more accurate? If you find the small flash hole is more accurate, you won't have F'ed up the entire batch.
