I have a 16 ga Stevens double on which the chokes are not marked. Does anyone know the standard bore diameters for the various chokes, ie Full, Modified, etc.?

Your help is appreciated!

Crash,

I have a 16 guage side by side that is imp. cyl and mod. It measures at the muzzles .661 and .653 respectively. Hope that helps.

Thanks BigBores!

Mine must be Full/Modified measuring .645/.653.

Crash....your chokes could bery well me Mod/Full but you can't tell for sure just by measureing the inside bore diameter at the muzzle. What you need is the amount of constriction and for that you need the inside bore diameter AND the choke diameter.
