    I'm trying to get some new shooters into trap and recently bought a BT-99 Micro which came with a choke having 1 "dimple" on the surface. When I measure it with a bore guage, it chokes at .028.

    I'd prefer to have the gun choked at somewhere in the area of .018 to .020.

    If so, which Invector Plus choke, i.e. how many dimples, should I buy from Browning?

    In advance, many thanks for your help,


    Pete

    Pete,
    On Brownings the following is a guide on chokes
    1=Full
    2=Improved Modified
    3=Modified
    4=Improved
    5=Skeet
    I am pretty sure this is correct only questioning myself on the Improved and Skeet.

    My INV+ modified choke measures .018" restriction and will grind up singles targets in either my XT, BT-99, or BT-100. Marc

    I would forget Browning chokes and get Briley or AnglePort. They measure dead on for constriction. Out of 15 Browning chokes I have, only 2 come close to what they are supposed to be. One of them marked MOD is only choked .010. That's .010 off as marked. They are junk IMO.
    My Brileys and AnglePorts are all within .0005 as marked. Plus on the pattern board they more then prove themselves with nice hot cores and a very even pattern. That's testing them with the same shell (Rem STS) at the same yardage, just a new sheet of paper.
    Browning Diana Grade and up chokes are made by Briley, but you're going to pay big time.
    By the way, I have 3 Brownings and a CG Combo. The Brownings have extended Invector Plus chokes and the CG has stock chokes. Browning a .742 bore and the CG a .735 bore. The CG on paper always performs better then the Browning's with Briley or AnglePort chokes. Forget the stock Browning chokes.
    If you pattern your chokes you'll start to understand. Just make sure your'e using the same shell on paper. Apples to apples.

    Thanks guys.

    Yes, I know from experience that going by the name (ex: Modified) can mean different things, which is why I go with the numbers.

    So -- Mike C. -- if I go with the Brileys, which ones will get me into that .018 to .020 range?
