RE: powder charges..
This is some interesting information. I honestly thought there would be more "magnum charge" shooters out there.
On the TV hunting shows, where they shoot the Encores and Pro Hunters, most of them are shooting three pellets and a 250 grain Shockwave I noticed. And they seem comfortable to some 200 yards or less in shots. Maybe it is the make and style of the rifle that likes the magnum charges?
