Mr. Charles E. Harris, otoh, is a well-known EXPERT on firearms, ammo reloading, cast bullets & other related subjects. AND he too is a published author, with a near-worldwide reputation.

Happy to rethink my statement.

However, can we limit the discussion to ballistic lab 'data', shotgun chambers, shell length and pressure. No need to obfuscate the discussion with alphabet.gov you purposely brought up to muddy the waters.

I am a fan of CEH and have a binder filled with his writings that I removed from various gun mags. I somehow missed those he wrote on shotgun chambers, shell length and effects on chamber pressure. Since you are a personal friend of CEH, could you ask what ballistic data he relied on which you base your opinion?

Looking forward to comparing, contrasting and perhaps rethunking.
