I agree Dean2, not a big deal at all.
SAAMI specs are designed to work within a specific tolerance, it's a number, nothing more .
Once the cases are trimmed to the chamber length, it's all good.

A good bore camera is worth its weight in gold for such encounters.

How would a bore scope catch that?

lol. Agreed. The first thing I thought of was carbon ring avoidance.

Chamber a fired round and put the borehole in from the muzzle.
You can see hoe close you are to max length when you open the bolt and close it .
I realized this when setting up my 40/65 for paper patching.

simple fix
Sounds like it was a simple fix Dean, keep the brass trimmed to 2.260 and all is good, load and shoot.

As long as the owner keeps the rifle, trimming after every firing would solve the issue, but if he decides to sell the rifle, he needs to make sure the new owner fully understands the situation.

I discovered this little secret when reloading for the 6mm xc 250-3000 Savage. Eighty bucks well spent, on that bore scope.

No need to trim every firing as long as know the trim length just like any other chamber .

Given that it was stated that the brass was too long after only one firing/sizing, I would trim all of the cases after the first firing/sizing, but yes, after being fire formed and trimmed, it may not be necessary to trim them after every firing/sizing Then again, with tolerances that close, it certainly wouldn't hurt to trim after every firing/sizing.
