This decision is harder than I thought... leaning now towards the 7mm08 in 20" barrel configuration.

Current bolt rifle stable consists of 6mm Remington (22"), 280 Remington (24") and 300RSAUM (22").
The 300 covers bullet weights over 150
the 280 covers the 140 to 175 middle.
the 6 covers 100 and below.
the bullet weight gap is 100 to 140 which a 6.5 would cover nicely...
and here i am looking at a 7mm08... sheesh
