I became enamored with the 310 about ten years ago. A friend came back from a gun show with a set of the universal handles and dies for .303 Brit and 7 x 57 Mauser....gave them to me as a gift (it cost him $12 for everything). I didn't use them for some time because I didn't know how......until the advent of the internet. I've located one more set of 30-06 handles and probably eight more sets of dies in the old military calibers.
My standard "range and field" kit consists of 310 handles, dies, extra decapping pins (necessary!), one pound of powder, 200 primers and about 250-400 cast, lubed and sized boolits. I adjust the dies before leaving for the field but also include a small hollow ground screwdriver in case more adjustments are needed. All of it fits easily into a .50 caliber ammo can. All I need is my fired brass and I can sit around camp in the evening reloading while my companions are counting how many of those expensive "store bought" cartridges they have left. Oh, they usually give me their fired brass......suckers.
The reason for the extra decapping pins? When used correctly, the pins last a long time. However, the tool handle is swinging in an arc which forces the pin to bend.......ever so slightly.......and then bend back again. I usually adjust the die so that it barely pops out the fired primer and no more. They're tough little pins but they ARE little, so hence the spares when afield.
