Miroku choke markings & steel

[russell]

I'm so confused . I have a Miroku Mk70 with 3 chokes on the way. Have been told the chokes would be Improved Cylinder, Modified and Full.

My main use for this gun will be ducks with steel shot. I assume the names given to those chokes above relate to shooting lead, and they have different names with steel. Looking at the Browning site, what those chokes would be is:

3 notches - IC lead, IC steel
2 notches, M lead, IM steel
1 notch, F lead, do not use with steel

But I looked at ozziereviews video on chokes. He had Miroku choke tubes packaging in close up, and going by that label they would be

4 notches, IC lead, M steel
3 notches, M lead, F steel
1 notch, F lead, do not use with steel

Those don't match! Can anyone shed any light on that?

Tom Roster's steel shot lethality table suggests IC-M for most of the shooting I will be doing. If the browning site is right then I should be fine with the first two chokes but if the label I saw on ozziereview's video is right then I probably need to buy another choke (IC steel). ?

I don't have the chokes in front of me so I can't count the notches.

I've attached info that may help, this is from my MK70 manual.

Thanks very much for that - what chokes did your MK70 come with?

Tried it out yesterday at 5 Stand with Mod (U) and IMod (O). Not too bad at all. Still experimenting
