You may want to consider a Mossberg 695 bolt slug gun. I'm not sure if they are still being made but there are plenty to be found used. It's a dedicated bolt action slug gun and very accurate. I use my H&R when hunting from a stand but when I'm stalking with a gun I grab the Mossberg because it's lighter and carries three rounds for quick follow up shots.
A good used one could be had for around three bills.
Here's one just like the one I have (without the silly see through rings) for $225.00
