Beyond max length but .050" off the lands

[COElkChaser]

I'm continuing load development in my 30-06 with 168 gr TTSX. After seating the bullet 0.050" off the lands I found my COAL, 3.346", was just over the SAAMI max 3.340". The bullet has a groove showing above the case.

Anyone else experience similar? What's the impact of the cartridge being longer than spec? They still fit and feed okay from my magazine, and I'm having no issue closing my bolt.

If you’re adjusting seating depth for a specific rifle you will almost always be over the SAAMI spec COAL, there’s no problem at all.

All 5 of my TTSX loads are showing a ring - the rings are to reduce bearing surface to minimize pressure and copper fowling, they have nothing to do with proper seating depth.
