whoo boy shotshell reloading prospect

[GoodOlBoy]

OK Wife and I were discussing the comming Christmas present (sorry guys the 20 I mentioned in scatterguns is already gone) and I decided maybe it was time to start handloading for my 20 gauge single shot since I cant seem to find the loads I want most of the time. SOOOO I need opinions. I am looking to start cheap to make sure I can stick with it, then in a couple years if all goes well I can think about some upgrades.

I was looking at the Lee Load-all 2 (and the add on primer feeder) and need some opinions here. I am only really looking at loading Heavy Field #6 loads for this prospect for now so changing out alot isnt a problem. Not mangum or nitro express or anything like that JUST 1oz 2 3.4 inch #6 loads, although I could settle for a decent 7/8ths #6 load and still be happy.

OK What do you think of this press for a starter press?
What shot should I be looking at?
What Primers?
What wads/shotcups?
I know there is a powder guide with the press that has recipies on it but still what powders am I likely to need to look at (just for pricing idears)
How do you (or do you need to) clean a shotshell hull for realoading?

And finally. . . . . . A good half my hulls are 2 1/2 inch hulls! They are even marked 2 1/2" I just discovered this today and no press I have looked at mentions loading 2 1/2s. Are these just to go in a toss bin for the garbage man? Yes I have checked them beside 2 3/4 inch hulls and they are shorter.

Oh and ok PS I have some old shells (I mean OLD) that have been kept clean cool dry etc, but for some reason the yellow plastic has turned blue/green. NOT the brass the plastic the brass still shines. The seem to shoot ok (I was in a hurry grabbed a handful to kill a chicken snake and afterwards looked at the half green half yellow hull and went "What the heck?" The green does NOT come off so I dunno if it was just a chemical reaction or what. They seem solid and everything. Should I just toss these hulls?

Thanks guys. For some reason the idea of loading my own shotshells appeals to me even more than loading rifle or pistols. I dunno why. Must be me gettin old.
