"Pelletgage"Field target IS great fun. But it's a challenge, too. You (like me) may think you are already great shot, and your gun is really accurate. You've shot all those paper targets in the yard, and gotten great patterns almost every time.
But get out there on the course with some competition, and you find just how much gap there is between you and someone with experience. Any little fault in the gun, scope, pellets, etc. will show up immediately, and your own ability to concentrate for a couple of hours and get shots downrange from different positions and ranges is difficult. But seeing the other shooters do it well is your motivation. And for the most part, field target shooters are more than willing to help you learn and provide advice about all the aspects of shooting.
You will likely find yourself getting a better rifle/scope, developing your ability to range, and searching for the best pellets. Not all the elements you need are expensive. For me, I wanted to do well with a "common" setup. Of course, my inexpensive gun has a new barrel, a custom stock, and about the third scope - the old argument of going ahead to get quality equipment from the start may apply.
The first time you clean a lane, beating a few of the people in a match, and finally getting on par with the better shooters is rewarding. I have met some great people and had a lot of enjoyment with this element of the airgun hobby. Highly recommended.
