Made from LW19 steel, whatever that grade compares to. It's a secret, I guess. Harder to machine, use higher RPM and a bit lower feed with muzzle flush coolant system. Good luck, if time is a constraint, if you chamber the "old fashioned" way (peck, withdraw reamer, brush away chips, re-oil, peck again). No offense intended toward the European board members, but European manufactures seem to be the most difficult to deal with, here in the USA. They're not forth coming with information and it can be nearly impossible to obtain repair parts (most anything imported by Beretta USA). US barrel makers freely state what steel is used, and regardless of how we feel sometimes, firearms manufactures make their repair parts available to the market. I go with a Krieger barrel over a Walther twice a day, every day of the week. The Krieger is cut rifled and the Lothar Walther is button rifled, not that I have any bias against button rifled barrels. If I have any doubts about longevity, I have the finished barrel Melonite/Black Nitrided. If I'm expected to machine it, tell me what grade of material it is (in terms that are familar, not some 'secret' code).I remember some remarks that the Walther barrels were different.
Anyone know the details?
That's the one. I've been interested in this subject as well because of non-lead mono metal bullets including air rifle.
I don't think it's "national sentiments" so much as familiarity. People like what they know and fear what they don't know.Looks like the topic is becoming a thing of national sentiments, time to leave!
Just to mention it, in Europe competition shooters, hunters and many rifle-producers often (mainly) use LW - barrels, and I have never heard that they were doing worse than their American counterparts ... Your rifle - competitions aren't automatically relevant for the rest of the world, even if they are called for world championships.
So, would a well fitted and chambered LW barrel last longer for say a 7RUM or 26-Nosler used for more than hunting or for a competition rifle shooting 3000 rounds per year or more. Would you be able to get 2 seasons out of it?
Having lived in Europe (England), I am aware more if the "sensible" frugality practiced there. If a barrel costs the same, fitment is a little more but lasts 2x longer it is cheaper per round. Justifying the difficulties of working the harder steel.One of best Norwegian shooters due to long range, known and recognized internationally, uses a 338LM with 32' barrel made by LW. He changed it after 4950 down the tube!! He uses constantly LW - barrels, because of his outstanding good experiences with them. So do others.
