Extrusion hone

Yup, LW50 barrels. I believe it is a PH stainless. Until you learn to machine it, you will say a lot of bad words.

They were junk, so never caught on.

The way they shot i figured they had to have done something crazy like cratex bullets, 80grit lapping, uneven lands from honing after rifling or something

I've leaned NOT to machine it unless the customer supplies the reamer. It can be cut but it's just plain harder than it needs to be...or should be, imho. I've tried different speeds and feeds as well as lubes. Do have have any secrets that you care to share about chambering one? Like
I said, I've done actually about a dozen or so. But that's just nonsense, right there...and for what benefit?

I’ve used a fair number of LW stainless barrels and found medium speed and heavier feed. If you let the reamer dwell or rub it’ll work harden and be a real PITA. Surface finish will look pretty poor but polishes quickly. I use a split brass mandrel and 320 grit at 1000 rpm with Kroil. Woody Woodall, the former fella at LW recommended thinner cutting oil with muzzle flush. I don’t have a flush system but did fine with high sulphur cutting oil with a bit of ATF and MolyDee mixed in.

Actually, I think that applies to most chamber jobs. Speeds and feeds are certainly more critical with some materials than others, though. Ideally, you should almost always create a cut rather than a chip or fine swarf. But I do agree with you. I just see no need for their whole thought process. Obviously, it can be done but at a cost in terms of tooling. A CNC lathe that can control feed rates would be very helpful, as always, but most of us chambering barrels do so by feel. No doubt, LW barrels "feel" a lot different than typical stuff. CNC allows for different feed rates as the reamer gets deeper into the hole as well, which would be great at times. Thank you for your input. It is appreciated.

I only chambered about a dozen too- maybe 10. Theyre the only barrels ive ever ruined a reamer on and when you call them its “german steel” and im an idiot for not chambering at 4000rpm

Woody was a douche bag!

"Woody was a douche bag!"

Darn it Butch, now at least tell me how to clean the mouth full of coffee out of my keyboard!
There are certain classic expression that just say it all without any additional adjectives and that is one of them.

Woody was a douche bag!

I bought a barrel from LW about a month ago, a prefit M98 CM in 9.2x62, and John at LW was very responsive, helpful and had the barrel to me in Kodiak within four days. It’s averaging 2.5moa with a peep sight and bullets swaged with .233 brass for jackets.

Anyway, long way of saying my recent experience with LW has been thoroughly good.



Ooops, sorry, totally off topic...

I'm sure it has to be much better now.

I wouldnt know and havent seen one lately either
