Does anyone use this sierra bullet #2275?
I have always heard and known of bullets changing a bit from lot to lot, but this bullet has been changed by their engineers by design or there is a mistake.
It is really screwing up my load data and trying to recreate known good loads.
I have 2 boxes on my bench: One box the bullets BTO, measured with a hornady comparator is .633. The other box, the bullets BTO, measured with same hornady comparator are all .663. That is a .030 difference, which of course conflicting my load data that I record.
Is this a common thing? Does it happen a lot and that much difference? These are Match grade bullets I assume, because Sierra calls them Match King.
