Beach? - farthest thing from my mind right now - too much snow and ice.

Your reference to impact locations I presume was for 100 meters. I've only ever shot one moose farther away than 100 yards, and most are less than 80, so the impacts are just fine for them. Deer, I've always walked them up on trails having fresh tracks so shots are under 50 yards.

The accuracy is less than I desire, so I'll try different patch thicknesses to improve that. As well, I have to shoot some heavier loads to see what they do to the regulation. The lower the pressure, it seems, the greater the vertical spread of the impact. Canting the rifle is something else that raises or lowers bullet impacts, as well as separating or crossing of the bores. Lots of testing to do.
