Not that you need any new information. You have some two dozen posts already.
But, I happen to have two custom rifles that sport Lother Walther barrels: 1) A remington 700 in .300 Win and 2) an '09 Argentine action chambered for 9.3x62. They are very purpose built guns. Hunting is the game here. I have heard from several smiths and shooters that Walther uses excellent steel and alloys in their barrels. While, I agree with others that they may not be the perfect choice for benchrest competition, they will more than suffice for a hunting rifle. My .300 actually shoots sub 1" groups with factory loads, regularly; one group measures .502" (I can prove these claims, I keep my targets). As for the 9.3, I had the barrel finished at 23" with a barrel band sling stud and adjustable safari type sights (banded front sight). Up top I have a 2.5X Lyman Alaskan with a German Post retical. Simple, effective for all types of big game. The first time I sighted it in at 100yds it punched about a 1" group. Very good for a set-up like this, if you ask me.
Given the caliber you plan to chamber for, and what it will be used for, I highly doubt that you will be unhappy. Don't let some of the Elites persuade you into thinking that anything less than a Shilen, Brux., Hart, etc. is necessary for your needs. Consider this: Most people cannot shoot well enough in a hunting situation to ring out the maximum potential of benchrest barrels, anyway; therefore, there is no justification, save for the right applications. Furthermore, hunting situations rarely allow for, or give just cause for the need of sub MOA accuracy.
As mentioned before in other posts, LW has excellent quality control; much higher than say... uhmm, Douglas (IMHO). I think you will be very happy. I highly recommend LW barrels. I have not bee disappointed. For the money, they are absolutely unbeatable.
