So if the primers can incrementally move enough that the accuracy could be impacted, then the sealant might have a value add.
However IMO, for these very small variances, the load would likely have to have .25moa accuracy at the onset to notice a deterioration due to this potential advent.
So for 99% of the time, the sealant is likely burdensome overkill step.
Thanks for providing this info. I have been wanting to store
a few thousand rounds just to have since you never know
these days. I wondered if they would still shoot reliably after
sitting in a closet for 20 yrs unsealed in a humid climate.
