With plastic cases a 10mm punch is giving me wads which are about .403" and a re a perfect fit with negligible force needed to place down the hull. A 11mm punch is giving wads which are about .435" and need to be pressed down. I'm assuming the interference fit will provide a better seal or is this too much?
When I do find a gun it will be reamed out to Improved/Cylinder choke.

Tried a selection through a full choke .410 today. 10mm wads were fine but 11mm too much for full choke. |The 1/2 oz /12.5 gram load patterned at 20 yards nicely enough but 10 grains of Lovex SO60 was not enough wumph to penetrate at that range. However it made little more noise that an unsilenced 12ft/lb springer.

10mm punch is to small and 11mm is to big
I use a top card punch that I got off e bay its just the right size

Most likely its imperial dimension .

I had another little session today with my mates full choke .410 .... this time with two loads:
One with 12 grains of powder, 11mm over powder and over shot cards but with 10mm wads.
The other with the same but with the first (driving) wad at 11mm and the rest 10mm.
The load with 10 mm wads patterned excellently, better that the load with the 11mm driver and also better than a factory Eley 3" cartridge. However 12 grains still lacked decent shot penetration so I will up it again. I should have my Belgium folder by Easter and will start fire forming brass. Following quadruple cross checking I found that a 22lr case holds 4 grains of my current powder so this has been added to my diy kit as a handy dipper. I shall pick up a .45 and 9mm case and see if they are usefull for shot or powder measuring.
