You WILL probably need a full-length resizer sooner or later. Neck sizing will eventually leave brass too tight in the chamber to be seated without stressing the mechanism.
I'd set up my die the thickness of a dime or penny off the shellholder and see how my accuracy is with the brass re-sized that way. After a 'number' of reloads the brass can be put into the rifle (with no bullet or primer seated) and you'll possibly see that it hangs up outside the chamber. Then you'll have to full-length resize. The penny or dime thickness may not be so much, however, that you'll get to that point with a FL die. But a neck-sizer will probably give you problems after several reloads.
You'll also need to watch your brass for overall length to determine when it must be trimmed. It can be trimmed as much as four times, but then throw it away -- they say -- before trimming a fifth time. I use Mobil-1 synthetic for case lube and it's not only cheap but it's effective at keeping cases from stretching. Just don't lube the shoulder, nor overlube the neck......'cause it'll cause dimples in the brass then.
Good luck.
