VersaMax loading port - limits?

[adamge]

Hey all. Looking for some advice.  I was watching a Taran & Keith video yesterday and noticed how far their loading ports extend into the mag tube on the bottom.  But they don't run VMs, so I want to check with those that have done this before. Is it OK to open up the loading port into the mag tube this much?  In the screenshot, you can see that the whole rim-base is visible.

 

 

Here's where I am at now (the one with the orange followed is latest):

I'm just guessing, so take it for what it's worth. But as long as the catch holds the shell in I think you'd be fine removing as much material as they did. I think the shell is still stabilized enough in the tube to both be loaded or loaded upon without causing an error.

I see Iam late to this topic and you didn't get many replies, I would tread with caution if you haven't done this yet, if you remove too much of the lip inside the shell tube the follower can cockeye sideways and sometimes come right out of the tube, watched my buddy screw up his $2400 shotgun this way, you can see you've already started to hit the mag tube in your bottom photo, some guys do remove a slight amount of the tube lip and have it run reliable, but too much like you see in the M2 photos of Taran's and you'll be looking at a VM paper weight.

Check out the RCI monotubes. They capture the follower so you can open the loading port generously.
