Requirements for Replacement of Currently Issued 5.56 M-855 and 7.62 M-80.

On a more primitive note, I ordered some Lapua 144gr for some tests...

Excellent! Looking forward to the results.

On a related note, I've wondered for some time how to do some valid comparative testing on 6-7mm bullets. The trouble is, insofar as FMJs are concerned, none of those available are of the same type or have weights proportional to caliber.

6mm ----- 80gr flat base in .243 Win.
6.5mm -- 140gr boat tail in 6.5mm Swede.
7mm ---- 140gr flat base in 7mm Mauser.
7.62mm - 147gr boat tail in 7.62mm NATO.

Today I came across Federal's "Fusion" line, with bonded-core, (protected?) soft-nose bullets, in the following calibers:

6mm ----- 95gr in .243 Win.
6.5mm -- 120gr in .260 Rem.
7mm ---- 140gr in 7mm-08 Rem.
7.62mm - 150gr in .308 Win.

I'm not sure just how worthwhile it'd be to test them, but the fact that all have the same boat-tail design, with weights roughly proportional, and made by the same manufacturer, loaded in the same basic case...
