I can assure you guys that getting to be proficient with a .410 is light years easier with longer barrels. I began using .410 S X Ss at age 8, and now 63 years later I have formed some opinions about them. I want the longest barrels on mine that I can get. I currently own three .410 doubles with 30" barrels. I've also found that using them on game requires quite a different shooting technique than I use with my larger bore doubleguns. With the very light .410s I begin my "move" towards the mount by swinging the muzzles on the bird from a low gun position. I fire almost immediately upon the butt being seated in my shoulder pocket. With bigger bore guns I have a much more deliberate move ......... mounting the gun before making the "move" and establishing lead.
My three current 30" barreled .410 doubleguns:
However, I am still searching for the perfect .410 double ........... maybe a 32" ????????
