Carlson's 12g Mobil Coyote choke, Mobil Rifled choke

[NickRigby]

Just wondering if anyone had any experience with the Carlson's 12g Mobil Coyote choke and Mobil Rifled choke.
I recently bought both for use in my Templeton T1000 straight pull with Sig Sauer Romeo 5 red dot. I usually stick with the IC choke, which gives good accuracy with slugs, NSI Primitiva give 2" at 50m, and a very acceptable killing pattern with Rio 12 pellet buck at 25 m. I use this mainly for pig control and thought it might be good to get a bit more range and accuracy with these specialty chokes. The promo for the Coyote choke said "tight groups with large shot at 70m". Tested them the other day at 50 m and 40 m using butchers paper with a 6" kill zone circled. Rifled choke opened up to just over 3" at 50 m, 12 pellet buck through the Coyote choke got 1 pellet on the edge of paper. Took it into 40 m and tried with Eley AAA buck, 12 pellets (50%) on paper, 3 in kill zone. A bit disappointed, so put the standard IC back in. Nice 2" group with slugs at 50 m, 11 pellets on paper, 3 in kill zone. Anyone else had experience with these chokes, am I missing something ? Given the need to change chokes between slug and buck with the Carlsons, I've decided that on balance, I'm better off just leaving the IC in. Overall a bit disappointed given the price at around $130 ea

I know nothing about those particular chokes but I do know that over constriction of the shot load can also widen patterns due to extra shot deformation . With every load combination there is a sweet spot choke that is not to loose and not too tight .
With slugs I found that if you drop a slug into the barrel and it lodges in the last 20 to 25 mil of the choke that's about the right choke for it .
Shooting slugs through tighter chokes will foul up the choke and degrade accuracy . Rifled chokes don't always give better accuracy as you may have already found out . I suspect that they tear up the slug more than they spin it but I can't confirm that . Just keep doing what you are doing as experimnetation is the best way to find out what works for you .

I wonder how it would go with bbs

Probably pattern like a garden sprinkler.

I just use rifled slugs.

I was in the same boat, but think I will save my money.

The 20" T1000 tested fine at 20 and 40yd with a variety of std weight slugs through the improved cyl choke.
Impressed me with 2 shots near enough touching at both distances, the other shot not far off, and more likely me.
Shot the tests standing, leaning against a pole to steady the body more.

Using one of those smaller-sized Bushnell red dots that don't affect the cheek weld so much.
The dot gets hard to see in bright sunlight, though.

Maybe Buckshot patterns better with that choke as it can be not so good.
The 9 ball stuff leaves holes that a rabbit could jump through but I bought a pack with smaller shot to try.
BBs were also not great, but #2 were tighter.

I always found #4s and smaller liked the tight chokes, so it's not a total all-rounder unless you change chokes.

Be sure to post any further findings here as lots of blokes may be doing the same and not testing everything.

A bloke on the big hunting forum did heaps of bench testing, running a scope and shooting slugs, he put me onto the improved cyl choke as he found it best.

That FHCK Outdoors pootube channel bloke said cheap turk chokes may be the wrong markings and sizes, been meaning to measure mine in case, can compare with my Beretta chokes as well, may do it now.
