If a #3 Bart or heavier - I prefer 22 max, if sporter 700 or say #2, no more than 23”
Personal preference for balance and blast - no can = no less than 21.
Speeds? Dumped WT at 400 yds using a 105/2850.
Only used 28.5 Varget but 26 on a No. 1
Enjoy your build. Up to deer, a 6 likely has no flies on a 6.5 with today’s bullets
