presumably 6.5 creed. yep that bc is a little better than hornady 147eldm at .697. although hornady says 1-8 recommended for their 140-147's.

I read that these will stabilize with a 1:8 twist, but Sierra recommends 1:7.5 because a lot of "1:8" twist barrels are actually slower like how a lot of "1:7" AR-15 barrels are actually 1:7.7 twist.

I have a 7.5 twist 6.5 CM. These things hammer. 41.8 grains of H4350 at 2.900" oal. When my service rifle was getting blow to the 7 ring, these only caught wide 10's and tight 9's on a 600 yard high power target.
That's what I like to hear, I can't read wind for shit lol

Thought the Nolser ABLR's had a BC in the low .7's? I've shot those, and my tube is a 1:8, handled them just fine.
Just couldn't justify the premium over the 142gr SMK's when they shot identically out to 600 my last F-class outing.
