I've been shooting off hand all my life in Silhouette competition so I'm used to taking shots without sticks at various distances. With sticks out to 600m is not a problem for me, practice will get you there, lots and lots of practice.
Lean a little in to them and make sure they are well set on the ground, depending the terrain they might lean a bit to the side. Sometimes you'll have time to adjust sometimes you won't. So practice with one leg shorter than the other to simulate the different terrains and scenarios you might run in to.
I would also recomment you practice offhand without the sticks, then shooting with sticks will feel easier, at least it did for me when I started using sticks, and I don't always use them.
Hope this helps.
