Considering purchasing a new Mossberg 940 Pro from my local fun shop (has the 24 inch barrel). Have been considering shooting Winchester Longbeard #6's or Foxtrot's Tennessee Twister 2 3/4 shells. For those of you who have shot the 940, I was wondering if there was any noticeable differences performance wise between the traditional lead shot and TSS to justify the price difference. Thanks in advance.
