Y'all recommend Bamarep a decent entry level over/under

Yessir, all good in the Gump.

I really like the feel of the Tristar ST. You guys know how some guns just "feel good" and it has great reviews.

I’ve been in your shoes before. If you buy a $700 entry level O/U , you’re gonna be handicapped from the beginning at each shooting station. A Tri-Star or Yildiz can only take you so far since the machining, fitting/assembly, and tolerances are crude compared to $3000+ shotguns.

I would go to 3-4 local shooting clubs in your area. Ask for the club president or someone who puts on the shooting events. Introduce yourself and explain your situation. See if they have a bulletin board where members advertise guns they’re selling. Most dedicated shooters are always looking to upgrade and sell their current O/U.

You’d be ahead of the game and have tons of confidence with a like new, used Beretta 686, Silver Pigeon, Browning Citori, 725, etc.. purchased for $1200-$1500.

Just my opinion as I bought a used 725 that was priced in my spending budget

Unfortunately for you, the answer to your problem is likely an auto rather than a budget o/u. That's not to say that a budget o/u won't work if that's absolutely what you need or want. But a new or used B gun auto would be a better gun for most. Less costly, less weight, less recoil, parts everywhere, adjustable stocks, and you'll probably shoot it better. Just something to consider. Also, don't fret over your decision -- the Indian always trumps the arrow, especially when it comes to shooting a shotgun.

Browning cynergy cx can be found for about 1700$ I was in the same boat as you and couldn’t decide if I wanted to go all in on a citori or not and bought the cynergy.
I ended up buying my son a citori 725 for his college graduation present and while it’s nicer wood wise I can’t tell the difference in shootability of the two.
