264 Win Mag LR bullets

[Nomosendero]

Great velocity with the 125 Badlands, I may need to try that one!

What are your thoughts on a 1:9 twist x 26" barrel spinning a 142 gr Accubond LR fast enough? Nosler recommends 1:8 twist for the ABLR but their load data test barrel is 24" x 1:9. Is the 0.082" longer than 140 Accubond going to be significant?

Fyi; I get 2 different ABLR SG's from Berger calculator (1.27) vs JBM calculator (1.633).
