Bib 108 gr.

[Gman]

Could anyone tell me what the B.C. is, on the 6mm. Bib 108 gr. bullets?

Thank you for the real world B.C.! But, Randy told me the 1 in 10" twist will stabilize the 95 gr., and a 1 in 9" or faster, twist is needed for the 108 gr.

In a plain 6 BR, an eight twist is fine. If you use a much larger case capacity,6mm. Ackley, 6-.284, .243 Catbird) then the extra velocity CAN blow up his bullets.,this is what Randy told me) I've shot the 108's in my 6 BR with excellent results at 2770 fps.- 2850 fps.
