About the twist... I've been looking at a bunch of
that recently.

The 55grain needs a 1:12 twist for optimization
The 62grain needs a 1:7 twist for optimization
The compromise comes at 1:9 twist, which is where some
modern firearms come in (except the M16s).

M16A1 - 1:12
M16A2/3/4 - 1:7
AR15 Sportsters - 1:9
HK G36 - 1:7
Steyr AUG - 1:9
FAMAS A1 - 1:12
FAMAS A2 - 1:9 (Note, they all have 7,9,12 barrel
options, this was just standard from factory)
Sig 550/551 - 1:7
FNC - 1:12 or 1:7 (factory order option)
IMI Tavor - 1:7
