I bought a fabarms 3.5 o/u several years ago, and it is a great gun. I have a trulock super full in the upper barrell and shoot Remington Wingmaster HD 3" 6's ..... In the Lower barrel I have modified choke with 1 1/2 oz load 2 3/4" copper plated 6's. The truth of the matter is I kill more turkeys with the modified barrel at 25 yds or less ..... I'd rather be shooting a volley ball at close range than a tennis ball pattern ,,,,
If you can find one of these guns .... they are already back bored ( they call it tribore) and ported ...... I've nver shot a 3.5 in mine ..... How dead can you kill a turkey without killing yourself...
Why torture yourself when a 3" will get the job done
A friend and I have been talking about the tristar o/u
