Grizzly Choke Tube

[janesy]

my grizz choke is tough to get out but it does. BUT, the invector choke for my buddies BPS slides right in.

I’m simply not going to shoot slugs out of mine until I get an IC choke or I’ll remove the existing choke if I get the urge to send a few slugs down the barrel in the mean time.

I don't know if I'm reading you correctly, but it sounds to me that you are thinking about firing the shotgun with no choke tube in place. Don't do that. That will screw up (no pun intended) the threads in the barrel and ruin it.

From a previous post they are supposed to take the standard Invector / Winchester / Mossberg type threaded choke.

They do indeed take the Invector / Winchoke pattern, but not Invector plus tubes.

I'm currently using Winchokes in mine, I like the knurled portion since it makes them easy to install and remove.

Who sells the Invector and Winchokes?

I figured that because the top of the threads are below the inside diameter of the barrel a slug would pass by without touching the threads.
I have no real need to actually do this so I’ll heed your advice.
Thanks P.E.

For those who have bought chokes, do they screw in to the bottom?
I have a Remington IC choke that screws in, but when it tightens up, it's not all the way down. I can feel a gap below the choke. In a side by side comparison, it looks like I need more threading on the Rem choke.
Do Invector (or other brands) have more thread?

I'll see if I can get a pic up later.

As you discovered it's not the thread that's the major difference, it's the length of the un-threaded portion of the bottom of the choke. Winchoke/Invector have a longer unthreaded portion than RemChoke do. If you screw in a RemChoke it will "bottom out" on the threads without the bottom of the tube coming to the bottom of the choke tube recess in the barrel. Looks to me to be about a 2mm gap, enough to start catching plastic, lead, etc.

A friend of mine kept shooting a shotgun with an ill fitting choke tube, eventually he shot the tube right out of it, which tore the threads in the barrel up.

Thank you. Time to go shopping again!
