CZ 527 Varmit .223 long chamber

Measures 1.960 from bolt face to lands. Measured 2 other 527's and there chambers were .025" shorter then mine.
Could I have worn out a barrel in 2,000 rds?
If so, where can I buy a replacement?
Must load ammo to 2.358" which is .010" from lands.
This eliminates using the magazine (max. cap. 2.330") but I use single shot loading when shooting critters so no a problem.
Would like to go a little bit more - .005" from lands but that doesnt leave much bullet in the neck.
Any help or suggestions would be greatly appreciated.

Not likely. If the rifle is still accurate with your favorite handload/s leave well enough alone. One of my .22-250 guns has no visible rifling for the first two inches of the bore. It still makes .75" three shot groups at 100 yards.

You don't have a long chamber, you have a long throat on your rifle. The standard solution is to have the barrel set back one turn and recut the chamber. Myself, I wouldn't worry about it, and I wouldn't seat the bullets so far out that they don't fit the magazine.
Never try to educate someone who resists knowledge at all costs.
But what do I know?
