You know I've never really given that a second thought before nor had I noticed much difference, but most chrome lined barrels are on military guns you're not generally using for accuracy shooting anyhow. So I wonder if there is actually a ,,Real difference, in accuracy between a chrome and non chromed ones??
Sounds like a good topic for research. Sounds kinda like comparing stainless to plain steel barrels, which I've never found much difference with,,except break in time,,,and Man, do those stainless barrels take forever to break in, there very hard steel!!! Just like chrome.
I had a DPMS 308 a few years back that took at least 400 rounds to get any consistency with, and that one had the 22" stainless target bull barrel on it. It shot crazy accurate after that though.
I'm still working on getting the 308 Mauser target gun I got from Bellson broke in, very slow to break in too. I've only got 150ish or so through it and it still needs more. I does get better each trip though, but I can only shoot a box or so at a time with this screwed up neck, so break-in is taking forever,, plus it's just plain friggin winter here 6 months out of the year and not really a good time to go target shooting right now,, @ -12 this morning when I got up,,it's way to cold for that chit !!!! IMO !
You gave me some food for thought on this one though j427x, as I've never really compared before. That would be hard to test unless you had a plain steel and chrome lined one from the same manufacturer to compare to each other. With a AR platform, not to big a deal, just change them out, but anything else changing a barrel out to keep all things even,, would take much more time to accomplish with to many other variables coming into play.
It would be worth trying though, especially for you guys that whip out those AR platforms and have the right tools. You could have 100% quality control to keep things honest and even that way, as opposed to using 2 different guns. Which I don't think would give you a honest comparison.
when ya going to get busy on that one j427x ?
