Bullets of different construction like solids often defy common reloading dimensions. Make sure you have enough bullet in the neck to keep the run out to a minimum. I would not concern myself with OAL. the 2.800 is a number that was conceived out of a range of bullets that fit in a SAAMI spec chamber. certain manufacturers mag length may have also been a factor. Fred probably can answer that one in detail. savage will let you seat a heavier bullet much longer in their magazine.
Remove the internals of the bolt. If you can, remove the ejector. Take a sized case and do not put a primer in it. Stick a bullet into the neck and seat the bullet into the case about an 1/8 inch. Place that into the bolt face where the rim is behind the extractor, chamber and see if the bolt will close easily. DO NOT APPLY FORCE. repeat until the bolt practically falls closed with no effort when you get close your increments should be a couple of thousands at a time. This method will give you the exact location of where your ogive meets the land.
From there you can work for your happy medium of jump and seating depth.
For what it is worth your findings are not unusual to me.
