6.5CM Ammo order

[572]

About to purchase several cases of 6.5CM ammo with the same lot#. I’m shooting a Bergara Ridgeback, 24” barrel 1:9 twist. The two options I’m buying is either 140gr ELD-M or 147gr ELD-M. Looking for advice of the best one to buy.

The reason for these two is for a LE order because of the low cost for us as well as those are the only two 6.5 options.

I ran both thru the Berger twist/stability calculator.
140gr G1 is “marginal” 1.4
G7 is “marginal” 1.18

147gr G1 is “marginal” 1.14
G7 is “marginal” 1.14

Any input?

I would recommend 1:8 for almost anything 6.5 creedmoor. I would honestly try to find 130's based off Berger's stability calculator, but if you are stuck to those 2 options choose the 140's

Thanks. Correction on my info. I’m at 1:8 for twist.
