Re: Barnes's Tests Prove Why Berger Hunting VLDs Are So Successful By Eric Stecker
There will be slight differences from lot to lot. The most common differences are in the OAL and the base to ogive measurement. This difference will be very small and should not influence performance but with all components you should confirm your tune when you switch lots.
Something to keep in mind is that we use one die and the same die for each bullet (until it wears out) so even though there are some slight differences from lot to lot the shape of the nose will be the same. This means that if you don't change your bullet seated die you will be in the same place in relation to the rifling since your plunger contacts the nose not the tip.
Having said this, it is always smart to double check your seating depth to confirm that it is the same with each new lot. We only change dies when they wear out so the vast majority of the lots will be the same but it is a good double check to confirm nothing has changed.
To strengthen your shooting skills go to the range.
