Have worked out some loads for several M/L for myself and family and friends.  
What do ya'll think of shooting a 2.5 ounce load with 85 gr of ffG?  Any ideas on approximate speeds?  It seems to hit hard and we like our pattern at 35 yards.  It killed 2 turkeys last year-both about 30 yards give or take.  I looked to see for ideas online, but short of buying a chrono, not sure how to answer that.
My brother's gun liked 75 grains of ffG with about 2.25 ounce load.  Only a 25 yard gun as it is a fixed choke.  Worries me about lethality, but it penetrated wood pretty well. 
All the loads are a mix of #7 15g/cc and  #5 lead.  
Just like to hear some thoughts.
