Thread: Impossible 6mm ??

A GT will easily do 3,000fps with a 105gr class projectile, loaded at normal length. But at 2.4” COAL, the boat tail will be well below at case neck shoulder junction, so a 95gr might be easier to make work.

Whichever projectile you use, your jump would be massive. I run 105gr Bergers and Targex at 2.580” COAL, about 30-50 thou jump with a 0.120” freebore chamber.

Photo below Targex loaded to 2.580” as comparison with a Berger 95gr VLD Hunting (boat tail about case neck shoulder junction) and then a Targex 105gr RBBT at 2.4”.
