Problem with Colonial Arms thinwall choke tubes

[Rob62]

I’m having problems with the Colonial thinwall choke tube that was installed in my Rem 870, 12ga. It seems that shooting buckshot and slugs through one of these thinwall chokes flares out the skirt of the choke and makes it darn near impossible to remove and re-install the choke tube.

Is anyone else having problems with this type of choke tube. BTW – A telephone call to Colonial Arms revealed that they do NOT recommend shooting buck shot or slugs through anything more than IMP Cyl. Choked thinwalls.

Regards,

Rob

I've always used ic as an informal choke limit when shooting slugs/buck.

If you want to shoot your slugs through a tighter choke, you might try their steel shot chokes. These are cylinder inside the barrel of the gun and have the choked portion as an extension out past the barrel. The purpose is to allow shooting steel in guns not approved for it. Seems like they would work for shooting other 'hard to choke' loads as well.

They work well in my Italian 20ga.

Follow up - Since I posted the above information I found out that in fact I did not have the "Thinwall" choke tubes installed. Even though the gunsmith who I got the work done through told me that's what it was.

Also the modified choke tube that came with the work, came in a plastic holder/sleeve that had it dentified as "Thinwall". I'm pretty PO'd about this error.

What initially got me to post this information was the fact that I had only shot about 30 slugs and about he same amount of buck shot through the MOD. choke tube, that was all it took for the deformation of the standard size (.794x44) choke tube skirt.

This seems like it should not have happend, at least not so soon. While I understand that a modified choke of any type is probably not the optimum choke to shoot slugs and buck shot through I've rarely heard of anyone having problems with choke tube skirt deformation.

That's what I'd like comments on - how many people have had problems with choke tube deformation while shooting slugs and or buck shot. What kind of choke tube, type of problem, # and type of rounds fired.

Thanks,
Rob
