Cartridge Efficiency?

So still waiting for wind to drop so I can run the 151HHT ladder. Interesting the SG for this bullet is 1.825 at sea level which is about 0.30 higher than the 156HH! So this will or should track great for terminal performance. I used 3300fps as prob velocity.

So is this another positive output of cartridge efficiency that results in increased SG?

Gday muddy
On the SG above & efficiency positive output

That’s one that cannot be underestimated on terminals

Caliber to length is so important which leads us to caliber to shank & so on

Yep Balanced pills & looking forward to the outcome of this

Cheers
