Re: Ithaca M-66, I want to try trap. Help
The comment re. uncompetitive (I believe) comes from the fact that you would be shooting against people with the "proper" tools for the job. The guns they are using are virtually built to shoot the game with optimal barrel length and choking to swing,balance and place the shot more effectively than other guns. Look at the assortment of golfclubs at a sporting goods store and you can begin to get the idea.
Skeet uses shorter barrels and open chokes for fast swing and spread patterns, a skeet gun is exactly what you do not want for trap where longer barrels and tighter chokes are the rule of the day.
In the shotgun world age and experience is more than a match for youth and enthusiasm; the old guys with the right tools looking at the new guy thinking "he will get there". I should know, I shoot hunting guns against purpose built trap/skeet guns with my more well heeled buddies; I give them a good run but my guns are a handicap to my shooting (like a handicap in golf); I will continue to enjoy my version of skeet/trap but will harbor no illusions about my score.
