Invetor Plus stock vs aftermarket chokes?

Bought a full set of Carlson's extended tubes. Nice, but not sure if you'd notice 'improvement' in anything other than ease of install and choke visibility.

Stock ones work fine.

Thanks, how about foster slugs? Do they group ok at 50-100 yards? Like minute of dinner plate at 100?
 
All depends what you are going with the gun. Briley chokes give me the best performance with steel shot in my waterfowl guns for clay shooting facory is finewith lead. Don't shoot slugs out of any of my inv plus so cannot comment there
 
Thanks for replies, I think ill use the stock IC and mod chokes and try a bunch of slugs through it. I have the fosters in almost every brand and also have brenneke from rotwell.

If the groups are too wide ill try a carlson extended IC.


Range report will be done in the following weeks or so.
 
Seems that way, but this info is for all invector plus:

Invector-Plus and Standard Invector choke tubes are
compatible with factory ammunition that has been
loaded in compliance with SAAMI specifications,
including magnum lead and steel shot loads, sabots and
shotgun slug loads.

and

All current 12 and 20 gauge Super X Pumps have a 3"
chamber and are designed to shoot all factory 2¾" and 3"
Field and Target loads. The barrel can safely handle both
lead and steel shot. Special rifled choke tubes are designed
for shooting sabot-type slugs.

These tubes are .730 (improved cylinder diameter for inv+):

Made by browning for invector +..
 
I run Briley extended chokes in all of my shotguns, but truthfully, the factory chokes aren't all that bad. The only factory tubes that I had issues with, were the DS chokes in my 725, the patterns improved a fair bit with the Briley chokes.
 
I will be patterning my SXP that runs the same chokes. Accuracy hasn't been bad with remington sluggers and the IC choke but I am a little tempted to try the Carlson extended rifled choke. At $70 I may just stick with what I have.

As an aside, Briley makes Brownings Invector Plus chokes.

Little confusioin here I think but could be wrong. Briley makes choke tubes also from time to time for remington but to remington specifications not Briley specs
To me the proof is on the paper. Shoot a factory browning mod for an example and a briley replacement it is quite a difference at least with steel shot
Is there are documentation that briley is currently making the invector plus for Browning you could share
Cheers

I believe it is a similar arrangement; Briley manufactures the chokes for Browning using Browning specifications. As far as proof goes, its written on the retail packaging on the invector plus chokes.

From reading this today it sounds like it is a yearly tender now and god knows who makes them year to year. Thanks for making us aware

There is a weak link in Browning shotguns, though, and it is with little question the Invector Plus choke tubes. To be fair, Browning is no better or worse than many other manufacturers in this regard. Firearm manufacturers long ago realized that scant few wingshooters ever pattern their guns and fewer still would pay an extra $200 a gun for high quality choke tubes. So, apparently Browning is forced to do what many other manufacturers have done: job out their choke tube work. To no great surprise, the lowest bidder gets the order. At the end of the business year, taking forty bucks out of the cost of every shotgun can really add up, meaning the difference between profit and loss or being competitive or not. All businesses go through this cycle, whether it is lawnmower blades or bolts and nuts in a home appliance, it is hard to put in additional cost and quality that no one will pay you for. The firearms industry is hardly immune from the pressure to get cost out of the box.

I'm inclined to suggest that factory Invector Plus choke tubes should be disposed of properly just as soon as possible if pattern quality at any range is of any importance to you at all. Browning Invector Plus "Full" chokes are simply not capable of true full choke performance that I have been able to produce in this series of testing.

Here is invector plus IC, at dusk around 8PM, the sun was lower than horizon. Front bead sight almost covered the whole paper at 50 yards, Brenneke rounds:

8.5 x 11" paper

I never had a problem with the pattern on any of the chokes that came with my SX3. I have two aftermarket chokes, both Carlson's, one is skeet (0.625 or ~5 thou construction) and light modified' (0.615 or ~15 thou constriction). I say approximately because the nominal bore diameter of a 20 gauge back bored barrel should be 0.630 but I have never had mine measured. I have tried to determine the exit diameter of the OEM Browning chokes, but I don't consistent results with my calipers. One day, I plan to take my chokes and barrel to Epps and have them measured using a dial bore gauge tool. I have a suspicion that my Carlson's light modified and my OEM modified choke have the same or very similar constrictions.
