The Manufacturing of Long Rifle Barrels

Postby john p k » Mon May 17, 2010 7:52 pm

Why hasn't the manufacturing process that LWRC uses on it's rifle barrels been applied to the barrels of long rifles. I have both Hart and Kreiger barrels that are superb but must be cleaned every 20 rounds or so. There is no way my rifle barrels have the life expectancy or ease of maintenance as the barrel on my 6A3. john

Sako (and Tikka) have been making cold hammer-forged barrels for decades. It's not a new concept in long guns, just not a very popular one. Button and cut bores are more popular than ones formed on a die since it's cheaper to set up the button or cut than it is to machine a new die.

Or, are you talking about the NiCorr treatment and not the manufacturing process itself?

Ease of cleaning to me is irrelevant since I cleaned my SBR every 1500 rounds and don't clean my bolt rifle until accuracy drops (which can range from 200 to 500+ rounds).

I'm an anti-cleaning whore. Cleaning just wears your barrels faster.

I was focused on the NiCorr treatment. I assumed it was part of the mnufacturing process. Cleaning long guns suck. Cleaning my M6A3 is a breeze. john

john....that might because the process is proprietary to LWRCi?

I think Remmington is using a similar surface conversion on some of thier rifle barrels. It's called TriNite or something like that. Not sure how it stacks up to NiCor, but it sounds like a step in the right direction.

But I think I agree with you TH317. I also think that they are using similar conversion.

Wow, every 20 rounds? I don't clean my barrel until I am back at home, and then basically with a bore snake except for a couple times per year I do a full cleaning. Accuracy is fantastic for hundreds of rounds. This is on a Remington Model 700. Barrel is cold forged, button rifled.

A barrel is cold/rotary hammer forged OR button rifled. Never both.

What is this "cleaning rifles" thing you speak of?

Peeing down the barrel and then dousing your 74 /w WD40 is SO cleaning!

Elbows, I was referring to my bolt action long barrelled hunting rifles.

Here is a technical article by Vern Briggs that will clear up some confusion and answer questions on Hammer Forged Barrels. Before we adopted these Purdue university did a study of very high end match cut rifled barrels and compared them to CHF barrels. They were tested in identical profiles on universal receivers. There was no difference in accuracy potential. However, most stainless cut rifled barrels have a service life of about 2000 rounds.
