I have 2 old rifles, both 6.5 caliber. An Arisaka and a Carcano, both have oversize bores, .268 instead of the normal .264, and bullets are hard to find. Last week I happened on some .268 bullets so I ordered some. Got them this morning and was going to load some and try them. Measured them and they were .266, not .268 as advertised. I have been on the phone with the seller and the importer, neither of which believes me of course. I measured them with 2 different dial calipers and a vernier mike. So now I am going to have to send them back and wait for them to confirm what I already know. I have been resizing .277 (270 win) bullets to shoot in them, made my own sizer, guess that will have to continue.
