Home Forums Hunting & Shooting Ask The Gunwriters What year was the Invector Plus choke introduced by Browning ?

I just recently sold a Browning Citori Plus over/under trap Gun.
It was made in 1991 and these may have been the first guns to have the plus chokes. This gun came with all sorts of features that before this were only custom add ons. Adjustable stock, high rib that could be moved up or down to change point of impact,recoil reducer in the stock that moved in and out and worked like a shock absorber on a car. And back bored barrels that being of larger diameter required these different chokes. Browning at the same time also made the choke longer to in theory ease the shot charge in to the choke transition and thus produce better patterns. Soon after all browning twelve gauge guns used these chokes which fitted right in with the use of steel shot. Some other gauges also use them, 20 for sure, not sure on the others. I forgot to add that because the barrels were of larger diameter the chokes also had to be larger in diameter to get the same amount of choke. I also find plus chokes to be a little on the open side, now weather this was done on purpose due to steel shot I can only guess. The only way to really know you choke is to put the pattern on paper. Which we all tend to avoid.
