Buzz, if I were shooting a flat of turkey loads a season, cost would be a factor. However, a three bird limit in Georgia is 3 shells. Shell costs to a turkey hunter is way down the list in expense. I can load 39 13/16 or 36 7/8 oz. .410 shells or 20 1 5/8 oz. 20 ga. shells with two pounds of TSS. My last purchase delivered was $116 for two pounds.
Around here, there has been a shift from 12 gauge by many knowledgeable hunters because of TSS and other tungsten based loads. Many go to 20 gauge or smaller. If someone can carry and shoot a 20 gauge weighing 5.5 lbs or a .410 weighing 3 lbs., 4 oz. and it is just as effective as a 12 gauge weighing 8-9 lbs shooting our granddad's lead shells at 40 yards, the move to subgauge is more understandable. I stopped carrying my SBE over 9 seasons ago and traded it away and gave a young friend my 835. Gil
