it's a fixed choke barrels o/u Bottom barrel marked 3 dots in a circle, top barrel marked 2 dots.Multiply each choke number by 4 and that will give you the amount of choke.
#5 x .004 = .020
#6 x .004 = .024
My 32 inch fixed choke has .024 in the bottom barrel and .032 in the top barrel.

You'll need to find someone with a bore gauge then.it's a fixed choke barrels o/u Bottom barrel marked 3 dots in a circle, top barrel marked 2 dots.
There's no numbers
100 grams of bbl weight.I'm a bit confused in P choke designations. In their chart they have IM and M both marked as 1/2 and triple dot in a circle for barrel marking for both.
So what would be the difference between 1/2 Mod and 1/2 Imp Mod?

I meant constriction wise since they both claim to be 1/2100 grams of bbl weight.
Look at the chart itself. Names are irrelevant given the math. Go by measurements if unsure. If you look at bbl weight vs label it will tell you if you have a 5 mm or a 6 mm restriction. 6 mm bbl is 100 gm lighter than a 5 mm bbl.I meant constriction wise since they both claim to be 1/2

Argue with Perazzi. Read the bleeding chart.There is no way .004" (.1mm) LESS constriction in each barrel adds 100 grams (3.5oz) of weight to the barrel.
I promise you you're reading or interpreting the chart provided wrong.Argue with Perazzi. Read the bleeding chart.

The chart is intended for the reader to look under thier country of origin.
The English call Modified 1/2 choke.
