Is there a difference between Invector and Invector Plus choke tubes?

The Invector Plus has about a 0.010″ larger bore than the standard Invector bore (0.740″ vs 0.730″). I have chokes and bores in both sizes and as far as I’m concerned, the Invector choke system is every bit as good as the Invector Plus system.

What is an Invector choke?

The Standard Invector interchangeable choke tube system offers consistent, dense shot patterns with the right constriction needed for the shooting situation. Threads on the breech end of the choke tube help prevent gases from slipping between the choke tube and barrel that could damage the choke tube and the barrel.

What choke does a Browning Citori use?

Are Invector chokes good?

They pattern very well. I would be highly skeptical of claims that Invector chokes aren’t any good. More than likely they are alibis for poor shooting, bad shells, or a gun that has the choke tube recesses bored out of alignment.

What do the numbers on a choke tube mean?

The notches indicate the choke tube constriction. A lower notch count means more constriction (tighter). A higher notch count means less constriction. 1 notch = Full. 2 notches = Improved modified.

Are extended choke tubes better?

Improved Shot Patterns Proponents of the extended choke tubes argue the extra length leads to tighter shot constriction and eventually tighter shot patterns. The Truglo Gobble Stopper is another popular choke for use in turkey hunting situations.

What does 4 marks on a choke mean?

Improved cylinder
A higher notch count means less constriction. 1 notch = Full. 2 notches = Improved modified. 3 notches = Modified. 4 notches = Improved cylinder.

What choke tubes come with Browning Maxus?

Fiber-optic front sight and ivory mid-bead. Four extended Invector-Plus choke tubes included (XF, F, M, IC) ABS hard case included.

Can you fire a slug through a modified choke?

cylinder choke would be your best bet, but slugs will work through a modified choke, it is only a little more constriction, and will cut down your shooting distance a bit.

Do extended chokes improve patterns?

The best available answer is that yes, based on best documentation available extended tapered portions have been shown to improve patterns. Extended parallel sections have been shown to improve patterns. High-quality extended chokes as a class have been shown to improve patterns anywhere from 5 – 20% efficiency.

What is the diameter of a choke tube?

The major diameter of the choke tube thread is 20 mm (.787 inch). The Optima-Bore/Optima-Choke system is typically used on competition 391 series semi-automatic, 680 series over and under shotguns and UGB25 Trap models.

What is an extended choke tube?

An extended choke tube protects the muzzle of your barrel from nicks and dents. A whack on a choke tube is preferable to a ding on your barrel everytime. In the case of many guns, barrel replacement is not remotely economical. With doubles, it can be extremely painful.
