At least you have all summer to narrow down that new rabbit hole you just peeked into. I have a similar situation with my 6.5saum. It shoots the 130vldh really well, but I have 3# of R26 and 200 140eol's just itching to be tried for Idaho in October.
You might look at the new 205gn EoL from Berger for the 300rum. I believe they have a shorter bearing surface than the ABLR and they have a BC of
30 Caliber 205 Grain Elite Hunter
G7 BC: 0.324
G1 BC: 0.631
Which is slightly below the published BC of the 210 ABLR, but who knows how accurate the Nosler BC numbers are. Pretty much a wash on BC, especially if you can get it moving a smidge faster with the shorter bearing surface.
