I've never had a < 6 lb. rifle before.
That's with a 4x32 Conquest, & Talley Lightweight Lows. I've had .308's weighing more that were fairly snappy, but I know stock fit makes a big difference in my case.
The plan is to load some 150 TTSX's over 45.0, 45.5, and 46.0 grains of Varget, & see how she does.
