What is the most common .410 99 barrel length? What is the least common length? Are all 1 line addresses a certain barrel length or can they be on any (22", 24", 26")? What was the original release date of .410 99 barrels? With the .300 Savage 99G release? Is there a guess on how many .410 99 barrels were mads? And how much is a 99 .410 spare barrel running at this point in time for purchase from an individual (average range cost)? thanks
