Problem with 22-250

[jo2015]

Shilen ss 26 inch.
A fired round measures .466 down at the base of cartridge,its supposed to be .470
A round that measures .465 will chamber and eject fine,but a fired round .465 hard to close and hard to eject

I did clean the bore,no difference,around 98 rounds fired,clean barrel 2 times since new

Prefit or did a gunsmith chamber this barrel?

I'll slowly make a half fast guess it's headspace.
Is diameter measured with calipers or a blade mic

Sounds like you need to adjust your die down to bump the shoulder.
