Land/groove configuration to shoot 215-230 hybrids in a 308.

[maxpower]

I've Been using 185BTs in my F/TR rifle, but am in need of a new barrel. I,m thinking of trying the heavier Hybrids next and will get the fast twist barrel throated to suit. Is there any preferred land groove configuration with the long bullets, 3,5,6 etc.

I am using a standard .30 ca Krieger barrel with 215 Hybrids in a 30-06. They shoot best 0.02" off. Using H4350 gives 2650fps and 5/16"
5 shot grps.

i am shooting the 215 hybrids out of a benchmark 3R with an 11" twist in a .300 wsm long throat. still working on load dev., and am curious to see if the 11" twist will work with those needles

Be aware that there is probably going to be a rule change in F-TR in the next yr or twqo limiting bullet weight to 201 or something like that.
