John Giles is doing mine (338 EDGE), I ordered it last month and only waiting on barrel to come in. His build quality is exceptional.

There is nothing wrong with Shawns rifles it just depends on wether you want to wait and pay a bit more or get one a bit earlier with exactly what you want on it. ie, Actions, Stocks, Barrels etc.
