Didn't get a response from anyone who has tried these, so I decided to take a chance and order a selection of the sporting clays extended chokes to try out.

So far I have to be impressed with the service from these people!
I rec'd my chokes within 5 days (from Georgia, USA) and they arrived in a perfectly serviceable hardshell, protective cloth-lined case.

Next, we'll see how they pattern.

They are reasonably priced, especially with our dollar being so strong. The Titanium version is a bit more expensive however, being more in the order of the cost of similar Brileys etc.

====================================================



PRECISION HUNTER
Our Precision hunter style chokes are extended, knurled and notched for use with a choke wrench. They are manufactured from high strength 17-4 PH stainless steel with an extremely smooth interior finish. They are suitable for use with steel shot from cylinder through improved modified. All chokes are marked on the head with the degree of choke and on the body with the exit diameter. There is no difference between the Precision Hunter and the Sporting Clay chokes except for the low glare black oxide finish. High quality, low maintenance, known constrictions and a reasonable price!

SPORTING CLAYS
Our Sporting Clay style chokes are extended, knurled and notched for use with a choke wrench. They are manufactured from high strength 17-4 PH stainless steel with an extremely smooth interior finish and are the perfect choice for skeet, trap or sporting clays. If your club so requires these chokes can be used with steel shot from cylinder through improved modified constrictions. All chokes are marked on the head with the degree of choke and on the body with the exit diameter. High quality, low maintenance, known constrictions and a reasonable price!

SUPER WATERFOWL
These chokes are extended, knurled and have a black oxide finish. they are available in three degrees of full choke- .030, .040, .050 and were specifically designed for use with steel and other environmentally friendly shot. this is the ultimate choke for LONG RANGE pass shooting of waterfowl. All Super Waterfowl chokes are manufactured from a unique grade of alloy steel that has a strength level of approximately twice that of 17-4. they are marked on the head with the degree of choke and on the body with the exit diameter.

I have four Trulock chokes that I purchased for my 28 gauge Franchi 48 AL.Have not had a chance to try all of them yet.The ones I have tried were at paper.They seemed to pattern very well.

One of the chokes I purchased was an extra full 28 gauge.This is the tightest choke I have ever been able to purchase for the 28 gauge.At the longer distances this choke shows great promise in the field.

I purchased my Trulock chokes from Londero Sports,Qucbec.
 
Jeepers, I miised the post 'cause I was outta town!
I LOVE Truloks!!:dancingbanana:
great people, super fast service, and very good looking, functional chokes at a competitive price.
What more can you ask for ?

Sorry I missed your post too popcan.

It may be a bit biased, as they are a sponsor of the site, but shotgunworld.com has an entire forum dedicated to trulock. I have not delved into it, as I do not own any trulock, and have not been shopping for any chokes either. Perhaps a bit late.


Hope they pattern like a dream for you.
What are you looking for in a pattern? 70/30? 60/40? 90/10?

I found my bone stock K32 patterning at 65/35 for me, and it seems to work for me. Dead dust, or complete miss!!!

Not trying to Hijack Popcans' thread, but if someone has a spare minute might the be able to explain how choke patterns work... ie 70/30? 60/40? 90/10? what exactly does this mean.

Cheers

This is referring to the % amount of shot that falls within a specified area.

ie, 60/40 means that 60% of your pellets should fall within say, a 30" circle at 40 yards, the rest outside of that. Depending on what ammo you use, you can pattern the chokes on paper with a circle drawn on it, and count the holes inside the circle. Then you can determine the distribution ratio.

Your desired result depends upon your intended application... hunting, (what type of birds/ducks etc?), different clay games, etc.
 
Thank You for the quick response Popcan =) Great explanation, makes perfect sense. Now is a 30" circle the standard diam. of a patterning circle or does it vary buy application?

Cheers,

Derek
 
I believe the 30" circle at 40 yards is supposed to be the optimum cone of shot for trap shooting....? Have to get some of the more knowledgeable shotgunners to chime in here.

Good patterning chokes should not leave big gaps in the pattern that birds or clays can get through. With a poor patterning choke tube, you'd be surprised at how you can think you are "right on" but the clay doesn't break.

And don't forget, paper patterning doesn't tell you anything about "stringing" ....

Basic Choke Information



What Is A Shotgun Choke?

A choke is simply a tapered constriction of the gun barrel’s bore at the muzzle end. The exit end of the choke is smaller by some dimension than the actual bore of the barrel. This difference is the amount of constriction. For example if the bore of the barrel is .730 and the exit dia of the choke is .710 you have a constriction of .020. The amount of constriction for a given degree of choke will also vary between manufacturers. As a general rule for standard chokes the total range will be between .000 and .045 thousandths of an inch under bore diameter. In the case of special purpose turkey chokes it can be as much as .100 or 1/10th of an inch. The length of the choke can vary as well. Most, but not all chokes will have an overall length of between 1.5 and 4 inches. Note that many fixed choke barrels marked skeet will actually be .000 or cylinder.
They can be grouped in 3 general types:
  1. Fixed chokes- They are made as an integral part of the barrel and cannot be readily changed except by a gunsmith and any alteration is considered permanent.
  2. Interchangeable chokes- These can be of the “screw on” style which is externally attached or the “screw in” which is recessed into the barrel. To change the degree of constriction you simply remove and replace with a choke of a different diameter.
  3. Adjustable chokes- This style of choke is adjustable throughout the entire range by turning a sleeve, which collapses or allows a collet to expand thus changing the exit diameter. A popular choke of this type is the Polychoke.
The most common design in use is the conical parallel. All Trulock Chokes are of this design. Shotgun Patterns

Patterns are normally expressed as a percentage such as 50%, 60%, 70% ect. This is the commonly accepted method comparing pattern density. In a 50% pattern ½ of all the pellets contained in the shell will strike inside of a circle of 30 inches in diameter. To find the percentage of any given load divide the number of hits inside the circle by the total number of pellets contained in the shell. You can obtain the approximate number of pellets any given load will have from a shotgun shell reloading book or you can open a couple of shells and actually count the pellets. Normally all pattern testing is done at a distance of 40 yards with the exception of cylinder and skeet 1 chokes in all gauges and all chokes for the .410 bore which are normally measured at 25 yards. Industry pattern percentages for chokes were developed using the preceding distances. If you want to compare any given choke to the industry figures you should do your pattern testing at the same distance. Industry pattern percentages for chokes were developed using the preceding distances. If you want to compare any given choke to the industry figures you should do your pattern testing at the same distance. The purpose for this is to allow you to select a choke that will throw a pattern that is as large as possible without having the pellets so far apart that the target can move through the shot string without receiving multiple hits. For shooting both game and clay targets you want a pattern that is perfectly even in pellet distribution over the 30-inch circle. Having said that, and after looking at thousands of patterns over a span of 25 years I could count on my fingers the number that I would call “even” and if these were measured close enough they would not have qualified. In this instance “very close” is excellent. Two exceptions to the preceding would be buckshot and turkey patterns. With both of these you are looking for a tight center cluster of pellets.
One thing to remember–The only thing that is consistent about shotguns is that very few things are consistent. Identical guns with the same degree of choke and using the same shell may not pattern the same. The same load between various brands of shells can pattern differently. Patterns will change when changing from hard to soft shot. Patterns can change when anything in the shell changes such as different wads, powders or primers. What I am trying to get across is that when you change anything such as brands, shot size, or components you will need to check the pattern as it could have changed, sometimes by an extreme amount.
Once you find a choke/shell combination that gives you the pattern you want it should remain reasonably consistent as long as nothing is changed. I am satisfied as long as the percentage stays within a 5% plus or minus deviation.
The below chart shows the relationship between the degree of choke, the percentage and constriction based on lead shot. Keep in mind that the percentages are a guide only. What you actually want is a pattern that is dense enough to insure multiple hits on your target at the distance you normally shoot.
Lead Shot Choke Chart

Constriction Percent
CYLINDER.00040 at 40 yds- 70 at 25 yds
SKT 1.00545 at 40 yds- 75 at 25 yds
IMP CYL.01050 at 40 yds
Skt 2 [light mod].01555 at 40 yds
MODIFIED.02060 at 40 yds
IMP MOD.02565 at 40 yds
FULL.03070 at 40 yds
EXTRA FULL.04073 at 40 yds
TURKEY.045 PLUS75 PLUS at 40 yds

Keep in mind that this chart should be used as a starting point only. Select the choke and pattern it. Change chokes or loads as needed to get the pattern you want.

Thank you very much for that Popcan, that was a very informative read for me, I am trying to absorb all the knowledge I can about this sport and posts like these really help me out. I am definatley gonna spend some time tinkering with choke and shot when I get my pal. I will be looking for what you have to say about those Trulocks you just picked up.

Cheers

Derek
 
The Trulocks I bought to try were: Skeet 1, Modified, Improved Modified, and an Extra Full.


I'm heading up to the cabin next week, and hope to pattern my new Trulocks then. If I am REALLY organized, I'll take some pics too.
 
Your pattern should remain constant. 60/40-65/35 etc. have more to do with gun fit and point of impact. Trap guns are ment to shoot high to accomadate rising targets.
