New Part # for Berger 105 Hybrid ?

[signut]

Just got a box of 500 of the Berger 105 Hybrid and noticed two things, a new part number and a new , faster twist recommendation.
Any input ? Different bullet ?

Different part numbers for boxes of 100 vs boxes of 500, so that might be it. The twist info was updated a few months ago, no change in bullets just a changed recommendation (they round down to the next lowest whole number).
