I never have been able to understand the Reason anyone would want to drop down to a 28 & then "Load it Up". A 20 gauge would be a much better choice for using 1 oz of shot. 1 oz of shot can be bought in either a Field or Express load in the 20 at much better prices than in the 28. Even if one reloads them components are much easier to come by & ore readily available. 1 oz in a 28 seems to me to be a problem much better answered with a 20. Just One persons opinion of course.
