I'll add one more you can't find. Hevi-13 in 1 3/4 oz. These white shell loads out perform the 2oz in my gun and choke. The 1 5/8 is just not even close. It just goes to show that the name brand everyone talks about is not the thing to focus on. You also need to know how that shell is loaded. I am dissappointed that they constantly change thier load. Clearly it is to generate more sales with guys buying all new loads. Thankfully I stocked up on any and all white shelled 1 3/4 oz Hevi-13 shells.
I agree that the knock down power of #6 is just fine. I've dropped gobblers like a stone at long ranges and so I would not want to give up apttern density with fewer pellets in the larger shots. Go with #6.
You can still get the Hevi-13 in a 1.75oz shell, but they do not hold a candle to the old white ones.
The old white 1.75oz shells were made for EnvironMetal by another company when they were being produced. They really liked to be choked tight, and I believe that they are probably the best made commercially manufactured load ever made. It was not uncommon to be able to get 200+ pellets in a 10" circle at 40 yards with the #6's......thats with a 1.75oz load people!
