I run an ER Shaw 7mm Rem Mag magnum contour on one rifle, and I can't get it to shoot under an inch, no matter what I feed it. It hits consistently at 800 yards with 150gr BT's, but its a pretty good-sized steel target. It doesn't feel well balanced with the Tupperware stock, but isn't too bad for hunting all day with.

I also have an ER Shaw 338-06 magnum contour on another rifle. It's pretty stout, with a laminated stock on it, but it balances much better than the 7mm. That barrel is kind of strange. No matter what bullet I try, as long as I have a max load of whatever powder, it is going to group well. Come down 0.5-1.0 grains and the groups open up to 2+ inches.
