If I'm understanding correctly, the following are the options:

Available Calibers and Barrel Lengths
.243 Winchester 20" and 22" (1-10 Twist)
6.5 Creedmoor 20" and 22" (1-8 Twist)
7mm08 Remington 20" (1-9 Twist)
.308 Winchester 16.25" and 20" (1-11.25 Twist)
.358 Winchester 16.25" and 20" (1-14 Twist)

They took the .243 out of consideration with the 1/10. I'm not against the .243 but I would have gone 6 CM for the 6mm bore offering.

7-08 would be ok for 162's but going 1/8 would have been good for anyone wanting to play with 180 eldm's and still would have worked for 162's.

Everyone has their own preferences. If they meet what you're looking for I'm sure they'll be fine rifles. The two bores that were the most interesting to me lost my interest with rate of twist and chambering.
