Some of the most fun I've had on Sporting courses has been with a pumpgun.
My better scores are with an O/U set up for the game, but numbers are not everything.
Were I taking a full choke 97 to a SC course, I'd....
Have a smith check it out first. The last 97 is a half century old now.
Given his blessing, I'd pattern it with loads of choice and establish it shoots where I look.
Using skeet loads of 9s for the close shots,trap 8s out to 35 yards or so and Premium loads of 7.5s for the WOD shots, I'd have fun and concentrate on the leading molecule of each target.
You may surprise a lot of people with how well you do, including you.
