Ported Chokes versus Non-Ported Chokes

Written by BlackBore Mark.

Now that we have considered the question of flush chokes versus extended chokes, let's discuss the related but equally controversial subject of ported versus non-ported chokes. Both sides have their advocates and detractors, but it pretty much boils down to personal preference more than anything! But the question is still unanswered so lets take a quick look at the advantages and disadvantages of both types.

For the non-ported folks, there are these to consider:

1. There is no sideways blast to distract or buffet the shooter and anyone to the side of the shooter.

2. Noise levels are less than ported chokes.

For the ported choke side, this can be said:

1. Reduces felt recoil (subjective).

2. Attentuates muzzle rise (subjective).

We can pretty much all agree that these few points are valid arguments as far as they go for ordinary ported chokes. But what if the ports in the choke actually help the shooter better their shooting game?

Obviously, BlackBore Chokes is in favor of ported chokes because of specialized ports (patented) that work for the shooter and enhance their shooting abilities. Yes, there is a certain amount of blast and noise associated with BlackBore Chokes, but it is not all that objectionable with quality hearing protection that one would use anyway while engaging in the shooting sports. That is just prudent and common sense. And, I don't know anyone that positions themselves so close to a shotgun shooter that they typically fall into the "blast zone", so to speak.

But what about the so-called enhanced features of the BlackBore Choke port that makes it a better choke than any other? I am glad you asked!

1. The BlackBore port is cut during machining in such a way that a knife blade is formed in the port. This blade slices and dices the wad as the wad/shot column leaves the barrel through the choke. You will actually see bits of the wad in the air and on the ground after shooting.

2. The wad is momentarily slowed down just enough that the shot completely exits the barrel without the wad. Without this "resistance" inside the choke, the wad would follow the shot out of the barrel and "blow" through the shot column causing fliers of the pellets.

3. Another benefit is that the pressure wave of the combustion gases behind the wad is prevented from "buffeting" the shot as it leaves the barrel. This further reduces the possibility of interference of the shot column by the "blast" wave as the shot leaves the barrel.

One other added benefit is that customers have told BlackBore that cleaning the choke is very easy! The ports act as "jet nozzles" that blow the carbon out of the choke leaving very little to remove from the port and choke body!

There you have it. BlackBore's take on ported chokes. Take a look at them if you are in the market for a choke that will help the shooter get better at his game!


BlackBore Turkey Chokes

Written by BlackBore Mark.

BlackBore now has turkey chokes! Or more specifically, those choke constrictions that are typically used by Turkey Hunters, Coyote Hunters and Card Shooters.

These chokes are manufactured of 17-4 PH stainless steel. This stainless is very tough, has the highest tensile strength and is very corrosion resistant. They come with a tough black oxide finish.The ports have the patented "knife-blades" machined into the ports that slice slivers off the wad as the shot/wad column passes through the choke. The ports/blades consistantly slows the wad with every shot and thereby enhances the separation of the wad from the shot colmn as the shot exits the barrel.This eliminates "flyers" caused by the wad hitting the rear of the shot column.

Turkey hunters using the #6 to #4 loads use the .680", .670", .660" and.650" constrictions at 40 yards. The coyote hunters using the larger shot typically use the .660"-.650" constrictions using plated lead pellet loads or the alloy shotshell loads. The card shooters shoot the 7-1/2's-9's in .680, .670, .660, .650 and .640. The .640 is a "special" design with 14 ports (while the others have 10 ports) and deep angled blades for card shooting.

BlackBore has chokes for all your shotgun needs, from Sports Shooting, to Hunting and Tactical.
