Everything else being the same, using the 300 grn SMK, the 338 Lapua remains super sonic to 2000 yards. The 338 Win Mag remains super sonic to 1800 yards.
How many here can constantly hit an 18 inch target consistantly at 1800 yards? Not many, I certainly can't. So what advantage is there to shooting a couple hundred yards farther.
I'm sure the extra recol of the Lapua isn't going to help you get that extra yardage.
Now look at the cost between the two, Rifle, Ammo, or components to load the round.
Makes you wonder if people don't buy the Lapua just to feed their egos.
