I replaced all my Invector Plus tubes with AnglePort chokes.
On the pattern board there is all the difference in the world.
AnglePorts throw a very even pattern. The Brownings on the other
hand are all over the place.
I have a custom one that they made me for my Remington 1100 Stan Baker barrel. Matched the ID of the bore exactly to what I ordered, and the constriction to what I ordered. Pounds targets when I do my part.
Haven't shot much with the barrel/choke yet, but 125 rounds and not a breath of plastic buildup in either the barrel (which has a mirror finish from Baker) or the choke. Using 1 box of claybuster wads, and 4 boxes of Gun Clubs.
Where else can you go and get a custom cut choke for 50 bucks? Most everywhere else will charge you nearly 2x the price.
