savage 220F!
20ga. bolt action
sells for around $450
I'd throw the best scope you can afford on it.
leupold makes the ultimate slam which has a ballistics reticle out to 300yds for your given slug load...50,100,150,200,250,300
if I had to do over I think I'd do the 1 piece dead nutz scope mount...
luckily I have a machine shop at my disposal...
