Calvan,
This is just my opinion, but one formed years back, so have been there and done that on the following.
In most all cases, do not follow the manufactures recomendations as per setting up a sizer in a full length die set!!!!!!!!!!
Because of manufacting tolerences, You stand a very good chance in over sizing your brass.
For example, say you happen to have a chamber on the big/long side of the tolerences and a full length sizer die on the small/short side. This would be worse case, but it can and does happen and when it does, not only does your reload consistancey go to pot, but brass life goes right out the window, BIG TIME!!!!!!!!!!!!!!!!!!
Rather, always set your full lenght sizing die just close enough to the shell holder to assure smooth chambering.
Using one sizing die for more then one firearm, may or may not work out well, depending on where they fall - +/- - on size.
When setting you full length die, do not allow it to touch the shell holder. Rather set it above the shell holder, possibly as much as 1/8". Size a case and see how it chambers. If it chamber without any problems, size and load the remaining cases.
AT some point after those cases have been fired a number of times, it may be hard to chamber or close the action on a loaded round.
It is very likely this will happen, at which point adjust the die down just far enough to again allow for smooth chambering.
You may need to go through this process 2 or 3 times over the life of that first batch of brass, but you will end up at the optimum position for your sizing die in combination with your press AND firearm chamber.
This position will provide you with the best consistancy and brass life FOR YOUR FIREARM, but may or may not work with other firearms in the same caliber.
Keep em coming!
