According to BH209 instructions, 100gr V load is max with a 300gr bullet. That is, unless I missed something. How was the performance with that load?
Varmint Hunter,
You are reading that wrong, this is exactly what it says.
CAUTION
- For bullets up to 300 grains DO NOT exceed 120 volumetric units of Blackhorn 209.
- For bullets above 300 grains, DO NOT exceed 100 volumetric units of Blackhorn 209.
- Bullets over 350 grains are not recommended.
So basically up to and including 300 grain bullets have a 120 gr volume maximum, anything over 300 grains up to 350 grains have the 100 gr volume maximum.
They have posted 120 grain volume velocities for all the bullets up to and including 300 grains. Notice the 320 gr White Powerstar at the bottom of the 26" barrel chart has a NR* (Not Recommended) in the 120 grain volume column.
