6mm Grendel Group Design Project

[bj139]

Why the .243" and not a .257" ?

In the quest for MV and BC, what are we loosing in hunting capability? Are sectional densities equal in 6mm and 6.5mm?

I thought the 6.5 Grendel already provided the optimal balance between target shooting and hunting performance.

That was my original question as well.

The 6.5mm (.264") is midway between the beloved 30 cals for us old timers and the newbies 5.56mm.

It is just the ideal compromise.

Target shooters are looking for the last tiny advantage so the 6mm has value to them.
