RE: Mossberg 100 atr
I bought a Mossberg ATR-100 in .270 when they first came out. It shoots 1-1.5" 5-shot groups with Fusion ammo (130 grain) and around an inch consistantly with handloads. I put a Leupold Vari-X III on it and a nice sling.
The deer I've shot with it were just as dead as they would have been if I'd have shot them with a high-dollar wood-stocked rifle, and I didn't worry about dragging it up the tree behind me when using my climbing stand.
The trigger is also pretty nice for and out-of-the-box inexpensive rifle, and the stock is more substantial than the Savage/Stevens 200's stock (my opinion) The action of the bolt is also pretty smooth, and I have had no binding issues.
