I haven't started to reload for mine yet, you might try searching for the following thread here in the Weatherby Nation (6.5-300 reloading data). In the next few months there are going to be some articles coming out in Shooting Times and Handloader magazines and hopefully the 2017 Hogdon reloading magazine.

The December issue of Handloader has a nice article about the 6.5-300 and it includes an assortment of loads.  I am really enjoying my 6.5-300 ultra light.

Welcome to the Nation!!! Thanks for sharing that info, I will now be anxiously waiting for my December issue to arrive in the mail. I also have a ULW in 6.5-300 Bee and love it.

Hope this helps?

I am using ADI 2225 (Retumbo, Reloader25) at 75.7 gn with 140gr Ballistic Tips MV 3090ft/sec whilst not super hot I am getting excellent results!
I am shooting a Arroyo RC (ex 340Wby) with 26 inch Hart varmint barrel

[224KING]

I get within 30 fps of your load,burning 23 less grains of R19 under a Berger 140 VLD out of my 6.5-284...and it's supposed to be a "Throat Burner"

It will be interesting to see how these new 6.5-300 throats do,over time,burning 80 grains of powder.

Posted on the ammo forum but these definitely belong here

142gr Accubond LR
H-1000 76.5 grains 93% fill rate
3205 fps
1/2" group at 100 yards

142gr Accubond LR
H-1000 79.5 grains
3516 fps (no pressure signs)
