Buffalo Bore tests from real revolvers and not test barrels.
Yes, I have read their advertising.
I wonder how they test to be able to assure us that they are "standard pressure." They give no numbers for that and are not SAAMI members.
"Real revolvers." There is an article in Speer manuals "Why Ballisticians Get Gray" with chronograph readings for the same loads shot in a variety of guns, every .357 magnum they could line up. There were differences of as much as 200 fps between guns of the same make, model, and barrel length. BB even mentions the phenomenon.
