Ed Harris pointed this out about primer pocket sizes which may be applicable if made overseas.
The SAAMI spec. for rifle cases using the large primer is 0.078-0.082. It is fine to ream them all to the maximum size of 0.082" using a No. 45 drill.
Small primer pocket rifle and pistol cases use a smaller flash hole size of .074-.078, but some European CIP (European equivalent to SAAMI) brass, such as Sako and Lapua uses 1.6-1.7mm flash holes.
Standard decapping pins are 1/16" needle bearings, or 0.0625, so smaller flash holes may yank the decapping pin from the stem.
Pistol cases intended for use with lead-free primers is sometimes found with large flash holes up to 0.12" in diameter. In my testing of Win-Clean (.12 flash hole) vs. standard Winchester cases (0.080 flash hole) in .45 ACP, there was no significant different in velocity, using 230-gr. lead cowboy bullets and a charge of 5 grains of Bullseye.
