Re: Powder recommendations
Hulls should be, if at all possible, from the Remington Premier STS Target line of ammo (the shiny green) or Premier Nitro line (the shiny gold). Mind you, Remington's Game Loads, Sport Loads and Heavy Dove loads have hulls worth loading as well.
These Remington budget hulls have steel bases instead of brass, so you definitely have to use a press that re-sizes the base. And these budget hulls come in both 6-point and 8-point variations whereas the whole Premier line are 8-point crimps. Some of the Remington budget hulls have a very thin brass wash (not even plating) that can fool a casual observer, but they are still very reloadable when properly sized.
The good news is that the inside dimensions for ALL* of Remington's hulls remain identical so as long as you use the same wad, primer, powder and shot weight you can pretty much load any Remington 2-3/4" 8-pt hull without segregating them from each other. Green Premiers, Gold Premiers, budget hulls both ribbed green and ribbed black... they will SHOOT exactly the same as far as downrange performance.
The budget hulls might give you three decent crimps before they take a dump. The Premier green and gold will give you at least double that number!
Winchester gray AA hulls are not junk but are close to it (two piece and may separate after a few firings), Winchester red AA hulls were superb but are no longer manufactured, and Federal hulls are weird because they aren't dimensionally the same throughout their full line. Some offshore hulls need smaller primers, and the use of American primers will stretch the primer hole after one loading so that you could get primers falling out (it's possible).
Geeez... I'm getting long-winded............
One last thing. Reloading for fine O/U and SxS requires very diligent hull re-sizing as these firearms have the tightest chamber dimensions. As you progress into pumps and semi-autos the chamber dimensions loosen up in order to help facilitate rapid feeding. In that regard, a $1,200 semi may not care if steel base hulls aren't always sized back to original dimensions.
nitesite.... you've been up a long time; shut up and get some sleep.
