Choke Selection and Information

Our Choke Info

Featherlite and SS Constrictions: U0 has most open pattern, U4 has tightest

Ü0 – cylinder/ Skeet* (in your face, out to 28 yards)

Ü1 – Skeet/Improved Cylinder* (out to 35 yards)

Ü2 – Light Modified/Modified* (out to 50 yards)

Ü3 – Modified/Improved Modified* (out to 65 yards)

Ü4 – Full/Extra Full (beyond 65 yards)

The labeling of constrictions is a little bit different than other chokes. For example, our  U1 will give a Skeet diameter outer fringe pattern. But, it will also  break targets as far and hard as an improved Cylinder due to the even pellet distribution.

How much constriction are the U0, U1, U2, U3, U4 in Thousandths of an inch?

As for the constriction measurements, it is different for every gun due to Jim making gun specific pattern geometry for each gun.

Jimmy Muller made the Constriction amounts different for each gun make and model based on how that gun performed, so thousandths of an inch is different for every type of gun.  As an average they are approx as follows:

U0 = .002",U1 = .005", U2 = .012", U3 = .022", U4 = .035

 

Featherlite:

• Our Featherlite choke is made Aerospace aluminum and is half the weight of Titanium, 1/3 the weight of steel.
• Ceramic Teflon infusion results in the hardest, cleanest choke on the market
• Specifically for clay targets & small game.
• Can only be used with certain shot size and material:
• Only use lead with max payload of 1-1/8 oz
• Only use shot size 7.5 or smaller (7.5, 8, 8.5, 9, etc… is okay)
• Nothing “bigger” than 7.5 (NOT  6, 5, 4 etc…)

Stainless Steel:

•  Heavier than the featherlite
• Can be used for both clay targets and hunting
• Many use target guns for hunting so we wanted to have an ultimate choke choice for hunting loads and non toxic shot, such as steel shot, Hevi-Shot, ITX, TSS, Heavy Weight Tungsten, etc.
• Made out of hardened Stainless Steel coated with “cerakote” rust preventative military grade coating.
• Can handle any shot size, velocity, material & payload ( NO LIMITS!)
• Can use lead, steel, hevi shot, bismuth, tungsten, ITX, TSS, etc
• Safe to use any size, payload, velocity, wad style, etc.

What Choke Should I Buy?

American Skeet- Ü0 (2 U0 for over/under guns)

Trap:

American Trap, Doubles - Ü1/Ü2

Singles:

Ü2 –  16 yard line

Ü3 – for Handicap (17 - 27 yard line)

 

Sporting Clays - typically a Ü0/Ü1, Ü1/Ü2 or Ü2/Ü2 combo

Ü0/Ü1 – for close targets inside 30 yards.

Ü1/Ü2 – for “normal courses” out to 40 yards.

Ü2/Ü2 – for “challenging courses” out to 50 yards.

Ü2/Ü3 – for “difficult courses” out to 60 yards.

Ü3/Ü4 for “Pro courses” past 60 yards.

3 Gun:  Specifically for 3 Gun Competitions

Made of Hardened Stainless Steel,  so they have no limits on shot size, can be used with Slugs & Buckshot.

HOSER - Inside 25 yards, similar to our U0 (Cylinder/Skeet)

FAR - for precision targets, has far and tight pattern, similar to our U3 (Modified)

Hunting:

DECOY – inside 35 yards (good for over Decoys or closer shots)

• Approximately .008" constriction
• Patterns with steel would be similar to performance of a Ü2 or Light Modified in comparison.

PASSING – 35-50 yards

• Approximately .025" constriction
• Patterns with steel would be similar to our Ü3 or Improved Modified/Full in comparison.

ÜFO/TÜRKEY - beyond 50 yards

• Approximately .040" constriction
• Patterns are tighter than a Ü4 and will outperform any Extra Full on the Market.  Best Choke for extreme distances on Ducks & Geese & Turkey; especially with Hevi-shot & Tungsten based shot.

 

Ammo/Other Info

In regards to Feet Per Second:  Lead Shot under 1260 FPS is best, For Steel Shot and Tungsten Shot for Waterfowl Hunting, 1400 FPS or less for the best pattern, any velocity exceeding this will start to blow patterns and open them up more than wanted. This is true for any choke, not just Muller Chokes. This is caused by Physics.

• Jim's top picks for most consistent ammos out there are as follows: B&P, Gamebore, Fiocchi & Remington.
• For hunting:
• Ducks & Geese: 3" 1-3/8 oz 1300 FPS, #4 & #1 shot sizes.
• Turkey: Winchester Long Beard #6's
• Long distance Pheasant & large upland birds: Fiocchi Golden Pheasant #5.

Back Boring:  When a gunsmith or machinist bores or hones out the barrel I.D. (inside diameter) to make it larger in size.  This causes a major choke tube issue! You can no longer shoot a “standard choke” that is made for that model shotgun.  It now would require custom chokes forever. (Jim does not recommend)

• Cleaners and lubricants Jimmy Muller recommends for his Choke tubes are Qmaxx Products, Rem Oil, Super Lube. These are safe on all of our Choke tubes
• If you are one who leaves your chokes in the barrel for extended periods of time he recommends good old bearing grease.
• Bore snakes are O.K. to use
• **If any other cleaner or lubricant is used and it discolors the Chokes they will not be covered under warranty

Lapping Compound:  Just apply a small amount to the thread area and using the wrench, spin choke in and out until it fits all the way in perfectly. Then oil choke and wipe off lapping compound.

• Use if your choke seems tight going into your barrel

Loosening chokes

• Use our choke wrench to tighten.
• Put grease on the threads to dampen harmonics.
