    I would get my load and stick with it at all distances. I like Redding dies.

    First off - I am by no means an expert, so hopefully some of them will chime in a help out a bit.
    that being said, I too, have used a dillion 550, using it i found that i really ended up using it one stage at a time and most importantly I hand measured the powder charge for each and every load for my 300RUM. I, too, like redding dies, i bought full length dies. the way i do it with my dillion 550 is to take preped brass, then lube that cases, size the case and put a new primer in, all in the first station. then i take the brass and add a hand measured powder charge. then once all the cases are full of powder i take them back to the press and put one in at a time and put them trough the next die to place the bullet.
    I don't think the powder charge on the 550 is anywhere near accurate enough for a magnum rifle, so plan on using a scale. I can't really help with specific powders or loads for the 338 but do a search, there is tons of info here.

    good luck!

    All of my dies are Redding, except for my 30.06 seater which is a Forster. All benchrest seater dies. I wouldn't hesitate to go with either.

    Powders: Hodgdon US869, Re22, Re25, H1000, Retumbo, Ramshot Magnum, VV N165, VV N560, and I would bet WC872 would be very good as well. I have the least experience with the latter.

    Make sure all of your dies are trimmed to the same length after sizing. I would also weigh each charge.

    I use the RCBS hand primer and the trimmer from Sinclair....think it is a Wilson. It is the one where you place the case inside the bushing, makes for the most uniform trimming as the case is not held with a pilot in the mouth.
