Shooting off a rucksack as opposed to bi/tripod.

[Canadiankeeper]

At the range? Bipod, sandbags.
Hunting? Bipod, freehand, day pack.
Work? Ruck, day pack or what ever I can use to help stabilize lol.

Use the best solution that works for the place you are shooting from period.

I find I can track moving targets and rapidly engage multiple targets faster off a rucksack. Ski pods are amazing and the pinnacle of bipod technology but only on a square flat range with 60 seconds between shots, not so much when you are guessing where and when the target will appear.
