Finally I have been able to get out shoot some trap these past two weeks. (I was unable to shoot last year due to shoulder surgery) After a minor gun fit issue was corrected I ran my first trap today from the 16. 1 bad round later(rest of squad wanted targets raised), I went to another field to shoot yardage(23) for the first time since July 2016 and boiled them all. Shot another and dropped 2 of the last 6. 48, I'll take! Really like my gun setup right where it is.
Depending on the course they could be report pairs or true pairs. Always two birds tho in a standard sporting clay setting.
Fixed full could result in a frustrating day. If you feel confident that your 20 can cover anything between 15 and 40 yards then that would be your answer. Or, depending on where you were shooting, I’ll borrow you a 12. I am not that way! I’ll help a brother out :)
Sporting Clays is more like skeet. You have a minimum of 50 targets usually. People do shoot sub gauges but I would say the preferred is 12. You can have targets at 15 yards all the way to 40+ yards, in my experience. Modified is a good all around choke. Shooting faster 1oz. Loads may help as well. Good luck and enjoy!
