I've played (very little) with a BAT in 375 Cheytac or 375 AM, I can't remember which, it did feel pretty tight, but I guarantee the guy who owns is will hunt with it; we'll see how it turns out. Stiller makes great actions, but as stated before I can't remember if they offer something big enough to handle the 408 or not. If you want some good info on Lawton I suggest going over to SnipersHide I search for "Lawton", the virtually unanimous results are that of a company spiraling downward quickly. I've never dealt with them & have only have experience with one of their actions in 408.
