Chrome-lined bore, chamber and barrel?

[joed]

A chrome bore will keep it's accuracy much longer than a non lined bore.

Lets say you have two .308 rifles one lined and one not.

They both shoot about 2 MOA. The unlined bore will start to lose it's 2 MOA ability from about 7 or 10 thousand rounds.

The chrome lined rifle could still be shooting 2 MOA at up to 15 to 20 thousand rounds.

I have some bad news for you. I realize the .308 doesn't burn as much powder as some other cartridges but I doubt you'll see the kind of barrel life you're talking about, at least out of an unlined barrel.

This whole chrome-non chrome thing is like political talking points.

If you can afford the ammo to wear out a barrel, the replacement barrel cost is very insignificant.

Silver2525, as far as a chrome-lined bore is concerned, it really depends on the type of rifle and what you planned on doing with it. For example, if the rifle is an AK or SKS that is going to get hard use in a humid or salt air environment, infrequent cleanings or shot with cheap or suspect ammo that is steel cased or might be corrosive then by all means opt for a chromed lined barrel if you can. If, at the opposite extreme, you are talking about a pampered target or plinking rifle that is regularly cleaned and properly stored then chrome lining is unnecessary and may even be detrimental.

"Chrome lined barrels are inaccurate" is a myth. There may have been some military rifles that had poorly chromed barrels that were inaccurate and started the myth, but I have two J.C. Higgins Model 50s in 30-06 that prove it ain't necessarily so.

The Model 50 was sold by Sears in the early 50s and used an FN Mauser action with a chrome lined barrel made by High Standard. They are both extremely accurate.
