Personally before going with the ATR (Night train)
I would rather pick up a stevens 200 with cal. of your choice, and get decent glass for it. You can also pick up a decent bipod for around 60-100 bucks.
I have a stevens 200 that I picked up just for the action, but afer playing around with it. I didnt really need to do alot of adjustments to get it to shoot .3" @100
You can pick these up in canada for just over $300.
Canadian Tire has a bunch up here for $259.
Thats just my .02
