To answer the title of the thread:

20 GA vs 28 GA IS THERE ALOT OF DIFFERENCE ?

In mass there is an 1/8oz. incrase.

In mass there is about a 17% increase.

If effective pattern diameter and range increase with the square root of the increase of pellets there is about an 8% increase in effective pattern area and an 8% increase in range.

If the effective range of a 28 gauge on Bobwhites is 30 yards then the effective range of a 20 gauge on Bobwhties is 32 yards.

I contend that gun fit, trigger pull, trigger creep, choke, and shot size have much more influence over effectiveness than the choice between between 28 gauge and 20 gauge.

Or, in other words, 6 of one or half a dozen of the other.

Best,

Mike
