I don't know about the 338lm, but I got one in 6.5 creed a few weeks ago, and I like it. The chasis is about three times as nice as the sig cross I used to own, and that's not a knock on the Cross chasis. The trigger is excellent, the carbon fiber hand guard is growing on me, but it's not like anything else I'd ever handled. It drips quality though, machining and fit and finish are exceptional. The folding stock mechanism is really, really smooth and solid. Locks up and unlocks easily, holds closed with a strong magnet. Tunable muzzle brake too, which I haven't even looked at yet, but it's very well made. The magazine cutout is a really cool look, definitely unlike anything else. I bought mine with the idea that if I didnt like it, I'd sell the christensen chasis and buy a traditional stock or an MPA chasis, but I really like it.
