Thread: Seating depth tolerances

I have just made about twenty rounds that are seated between 1.5 and 2 thou deeper than I intended (I didnt zero the verniers)
Do you guys think this may have an impact on accuarcy or is that within tolerances?
These were supposed to be used for my ballistic calibration so I want them to be a pretty real representation.

Cant you run them back through and seat them a little deeper?

No

Unlikely to make much difference. Projectiles in the same box are made in different dies so they all vary slightly so you are likely to get minute differences between rounds regardless. I assume that you will be shooting more than one cartridge for each range so this is your final check.
GPM.

At worst it might effect group size but not trajectory / ballistics

No, as above

Thanks guys

Unlikely unless you have a particularly fussy rifle.

My rifles aren't very fussy.
One had more than 6500 rounds fired, another more than 5500, without adjusting seating depth.
As the throat eroded it would have changed the effective seating depth.
Didn't seem to change the accuracy.

The biggest source of error is usually the nut behind the bolt.
