I owned an ADL and I will NEVER touch one again, worst finish of any rifle I have ever seen I was fighting rust all the time despite regular cleaning and oiling, I would not even give it the dignity of making the list much like the 770. It was a shooter though, if only they made it in a stainless I probably would have loved that gun.
They do make it in stainless. Sportsmans Warehouse has had them for 3-4 years and I've seen them at Dicks too. Last price I saw was $479 ish with a cheap scope.
For the money the new Ruger gets my vote for a budget rifle. The Tikka is a very good choice, but I'd put it in the mid levels for both price and quality. And probably the most gun for the money in the $500-$800 price range.
the Tikka shouldn't cost anymore than a Ruger American, or a Marlin X.
The Tikka stock is far better quality than the others, and easily justifies the added expense.
