At 12 pages worth of PDF file, the "revolver checkout" is a major update. There's pictures. There's side-notes on everything from special needs for black powder, reloading tool compatibility, make and model-specific data, and at the end a one-page outline of what kind of recoil and ammo performance you should expect with various weight classes of 38Spl and 357 guns.
There's special notes scattered throughout on various gun types, everything from the Colt Walker to breakopens to aluminum-frame snubbies.
There's...a lot . Page 12 is a one-page re-hash of the whole checkout procedure as quick bullet points to take with you to a gun show, gun shop, post-apocalyptic back alley or whatever . Despite this "short form" I recommend reading the whole thing once, to get the various theories and advanced notes down before going shopping.
NOTE: you can download it locally - look for the "file" menu, top-left corner area below the color google logo. This is also where you can print it cleanly.
