I shot A Marlin 512 slugmaster for many years.Gun shot very well(Brenneke gold 3"and 2 3/4 lightfields,Wincheter partion gold where terible flew everywhere)Action was a little ruff and trigger was rotten.I finally found a Browning A bolt.Best made shoots extremly well(3" lightfield commanders)Trigger and action are same as browning A bolt rifle.Marlin ,Savage,and Browning no longer are manufacturing bolt action slug guns,but If you can find a used Browning that would be the way to go,unless you have big $$$ and can purchase a custom made Tar hunt.
