28 ga Repro

[Bill Murphy]

Edgar, yours are proper mod and full. However, 28 gauge Repro fulls are usually .039, twice a normal full.

Bill, why are 28ga Repro's tight and how tight should a 28ga Full be? Is .045" like mine too tight? Ballistically, and in general, do 28ga Full barrels have to be near .045" to be effective?

I found a chart online by googling -choke constriction in shotgun gauges that appeared on this forum. It went from 12 to 410 and as the bore got smaller so did the amount of constriction needed to get a particular choke designation. For instance .045 for full in 12 but only .017 for 410
It may be that .045 in a 28 is doing just the opposite of what one would think.
The so called turkey chokes i have tested in some guns shoot a weak mod. pattern
Each is individual to the specific gun and load.
