A 22-inch barrel is my choice in a 308 Win brass based cartridge. The 7mm-08 ballistically betters the 308 Win on one end and the 6.5 Creedmoor on the other. Notice I said ballistically, as for hunting use they all have their own individual benefits.
A 20”-22” barrel with 8, 8.5 or 9 twist on a 7mm-08 may be the best carry, reduced recoil, long range payload (bullet weight, BC and WD) out there.
