After doubling twice in a row on my first buf hunt with my 500 double I vowed "never again"I purchased a SXS shotgun,had the triggers functions reversed and went (and still go) clay bird shooting using the rear trigger first.You would be amazed how fast you can move to the front trigger.You can easily dust a big chip in the air from a first barrel hit-asumming a true aim,which is where I usually have the problem.The tension,heat and sweaty hands
that happen (to me at least)when close to dangerous game are never duplicated at the range or wing shooting-hence my rear trigger first procedure
