I have been running some Federal 7/8 oz of 6 shot for sharp tails and am currently loving the combo. Pretty much everybody that I have talked to that owns a 28ga agrees there is just something about it that works. I had better results on the trap range with more of field load like the one above than I did with the 9s I had been using.
What turns me off about the start up cost is the fact that Hidalgo mentioned it was easier to have different presses for different lengths etc. If it was more like a metallic setup where I could just buy a set of dies and change gauges quick and be done i would be all over it. I am sure it is addictive, my rifle reloading has turned into my favorite pastime and gets a fair share of my gun money already.
I'm sure I probably will get into it at some point I just decided there other things I would rather spend my money on right at that current moment.
