REPRO CHOKE BORE DATA

[Gary Laudermilch]

This thread and a rainy day caused me to pattern my recently acquired 12 ga with 28" IC/Mod chokes. At least that is how they are stamped. I have measured them at .006/.012. I did not have enough time to do a thorough job of patterning but enough to get a good feel for how the chokes perform. I used loads that I have patterned in other guns so I have a feel for the loads capabilities. The patterns achieved were consistent with the choke measurements. The open choke came in at a strong skeet and the tight came in at light modified. A delightful clays combination.
