Remington 870 with a Hastings cantalevered rifled barrel topped with a 3-9 scope and shooting lightfield 2 3/4 saboted slugs. It kills everything I hit with it. I get good groups out to 150 yards. (I feel like I just did a commerical!!)
With all the time and range work I have put into the Savage I have already made the decision that it will be my choice for this season.
Without extensive shooting, and putting up alot more money for slug testing in the Browning, it is tough to say which gun is more accurate. The only serious head-to-head shoot off results I have seen found the Savage to be the most accurate factory bolt action rifled shotgun. (The test featured the A-bolt, Mossberg 695, Savage 210, and Marlin Slugger.)
I can definitely say that the A-bolt looks a heck of alot nicer though. It also handles slightly better in my opinion. The reality is I don't mind really banging the Savage around in the woods. The A-bolt would be a little different story.
Mossberg 500 w/ fully rifled barrel and Bushnell 1.5-4X 32 MM scope, and 2 3/4 lightfields.
Mossberg 500 smoothbore with the same scope mounted on the receiver, and Remington 2 3/4 slugs.
The 'basic' smoothbore shoots as well as the rifled barrel @ 50 yds; the groups spread a bit at 100 vs. the rifled barrel, but I can still put 3 in an 8 in. circle. The rifled barrel its more like 2 in.!![up]
