I do not have a double, but one day I will have one. I have shot with doubles and enjoy shooting them.

My question is: What is the chances that a double will regulate with factory ammo? My personal opinion is that you are lucky if it regulates with factory ammo, unless it was regulated with a specific make of ammo and use the exact same ammo. For me the only way to realy regulate a double is to reload.

What is your opinion and experience?
