The AICS goes about the same as your Wyatts. Appreciate the info. I have an AICS setup on the kids' 700 in 300 savage, and am wondering if there's enough capacity in that case to burn R17 behind a heavy bullet like you're doing.
A lot of it will probably depend on how long the throat is in the rifle. You will need to seat them pretty long to gain some powder volume.
If I had to load near 2.8" standard 308 OAL, I doubt the 215 or 208 grain bullets would be very viable.
