I have collected a few Lyman/Ideal 310 tools to use on a few old rifle calibers that I have, just for nostalgia. In finding some two-die sets that were probably offered for people that had a 30-06 set for instance, and then wanted a set for an 8 MM Mauser or a 7 MM Mauser that had the same adapter die and priming chamber as the 30-06 set, I have come across a couple of these two die sets that say "Tru-Line Jr. Press Dies" on the box. Is there any reason I shouldn't use them in a 310 tool and what is the differences in them? They all seem to be later sets with a combination neck sizing/neck expanding/primer removal tool, and the traditional double adjustable bullet seater/crimping die.
