Long Light Bullets (e.g., Spanish CETME and US FABRL) a dead end?

[BluntForceTrauma]

Sounds similar to the Swiss RUAG 7.62x51 AP bullet design?

Boom, yes! Almost exactly it. Now just Grendelize that baby!

But tweak it so there is a bit more copper in the boattail, sort of like Nosler's Accubond LR. That way you'd have a bit more weight in the tail to promote both external ballistics and tumbling in soft tissue.

Did a search and realized I was advocating this bullet a while ago. Post #388.
