they DON'T have chrome lined barrels, but remember, in a match grade rifle, you don't WANT a chrome lined barrel.
Chrome lined barrels DO last a lot longer, but generally speaking, there is a certain loss of accuracy. Of course, Uncle goes with the Chrome lined barrels for reasons of durability.
Taking that into consideration, I've just opened myself up for flaming from some of the idiots that hold MilSpec as Holy Grail.
There are people out there that would buy a screen door for a Submarine if it was genuine MilSpec.
One thing about a chrome lined, if you're lucky to get a GOOD one, (chances of winning the lottery are about the same as getting a good one.)They WILL last a lot longer.
In about 10 seconds from when I post this there are going to be a large number of guys that SWEAR that their chrome lined is capable of sub minute accuracy. Show me the targets. SOME may be, but damned few.
For a varmint or target rifle, go to the competitive forum. Ask them how many of them use chrome lined for varmints or serious competition. MAYBE 1/2 of 1%.
