Gang,
Federal #9 TSS 20 gauge shells are appearing everywhere this year and are going for moderate prices. I recently found them at Academy Sports for $29.95 for a box of 5 which qualifies for free shipping or store pick up. Federal is also offering a 10% rebate on the shells which brings the price down to $26.96 ($5.39 per shell). Several years ago when I handloaded some TSS shells, it wound up costing a little more than that per shell.
Simply stated, the use of 18 gram per cubic centimeter Tungsten shot in shotgun shells just might be the most important change to our sport in several decades. I am not an advocate of taking long shots at gobblers, but the real benefit that I like is the incredible pattern density that the TSS shot are able to create. The patterns just do not have anywhere for a turkey to hide in them like lead shot used to.
Whatever shells you choose, address your own sensibilities and know the limitations of your pattern/distance/choke/gun/gauge.
Cheers
