Title: Choke tube question
Post by: Gman on January 31, 2024, 09:00:32 PM
Does stopping the wad from spinning (in either a clockwise or counter clockwise rotation) while exiting the choke tube play an important part in keeping the pattern consistent or possibly tightening it up?

I have a machinist friend that will mill 5 or 6 shallow lengthwise grooves (parallel to the bore) in a factory full choke tube for me & I was curious if this could possibly help tighten up a pattern.

This would be for a 20 gauge Mobil choke tube shooting "old school" lead.

Matt Tyree on YouTube has done some tests with a tube that is straight rifled. It doesn't pattern well.

Just watched the link that you posted. He was shooting buckshot, but I might let my buddy mill in some shallow grooves & shoot some #5 and #6 lead magnums just for shyts & giggles.

I tried rifled choke tubes a long time ago with no luck at all.  Indian Creek has steps. They work very well. I have tried everything except a fully rifled shotgun barrel. Which now I may just have to. I have one on my 1100. I believe that just about every choke manufacturer makes claims that their choke imparts spin or slows down the wad.

Were these "straight rifled tubes" or the ones with a twist made for slugs?

Do Indian Creek tubes have rings cut in to separate the steps?

Yes, Indian Creek has steps 3 I think.
The one that I was talking about had straight cuts like rifling but not spiraled. I am trying to remember who made them. The guy that I am thinking about maybe "Tom Casey"

Interesting.

Do the Sumtoy replacement tubes for a factory production barrel (like my Benelli M1 Super 90 Monte') have the straight rifling or is it a custom made tube?

They do,   When we came over from the target world to the hunting world we used the same technology to develop our chokes.

Thank You for the reply. I will call you in the upcoming week to ask some questions & probably order a tube.  Thanks!

I have a factory Remington straight rifled turkey choke from back in the day that shoots excellent with lead shot in my 11-87.

No , I don't see how it could.
The shot is way ahead of the wad when it exits the barrel.
