In the process of getting a 6.5mm - 300 Win Mag built. It will have a 1-8 twist barrel & be finished in the 24 1/4 - 24 3/8 range. Neck is throated to have a COL with a 140gr Accubond of 3.550.
Looking for powder suggestions & load charges.
Retumbo, RL25, H870, AA8700 & US869 are the slowest powders I have in the cabinet.
For those of you who shoot this cartridge I'm looking for a good baseline.
This will be a deer hunting rifle.
An accurate 3150 - 3200 FPS with a 140gr is my goal.
Thanks
