Thank you very much. cordell
I measured a fiocci just now, and got .627 does that come out right in mm?

Your welcome.
TSJ,
.627 = 15.92mm. It is under specs.

cordellHello Lefteris, and TSJ,
Thanks for your help regarding the rim dia. of the .32ga shot shell. Cartridges Of The World (page 390 6th Ed) puts the rim dia at .653
Lefteris yours with a 0.40mm tolerance puts the MM conversion to inches (thou) very close. 16.10mm= .633857 + the 0.40mm tolerance puts it at .649605thou + or -. giving it a difference of .003395thou. from COTW's.
TSJ, your Fiocci is undersized but I am sure it doesn't fall down the bore

being only .026 thou or .6603999mm undersized.
I am trying to come up with a two barrel set on a Martini conversion and was looking at the .32ga as an alternative to a companion rifle barrel but in reality I will probably go with a set in 2 rifle calibers instead. I do thank you both for your help, and God bless you and your families. cordell
