I have never done dogs or chuck so anything I say on this matter is only from what I have read.

You said
"I look at 1000 yard rockchuck shooting as nothing similar to varmint hunting. Those aren't hunting or varmint rifles. Most of them also need a benchrest to accompany them."

Yes on these distances they do use bench rests and no they are not hunting rifles or your standard out of the box varmint rifle.

It all sounds fun to me though
