Will a 8 twist shoot 140 accurately? What would be an ideal long range bullet and weight?
Yes...
I’ve owned and/or loaded for 7/08s in 8, 8.5, 9, and 9.5 twist. All have had zero issues shooting the 140-162/168 class bullets. I played with the 180 ELDMs in the 8 and 8.5 twist barrels as well. Honestly a crap shoot there if it’s going to offer sufficient stability in all weather conditions.
Not sure what constitutes long range to you or the intended use, but a 162 ELDM out of a 7/08 would be hard to beat. The old school 162 AMaxes, 7/08 combo is still one of my favorites.
But with that said IMO you need to be running in a DBM with binderless mags to get the COAL where you need it.
