dies neck or full length

[scooterman27006]

i know i keep bringing up hot topics that i should already know the answer but i cant help it - i keep reading too much about this stuff and need pro info on it in order to make my mind up for my way of reloading - i dont have a lot of guns in the same caliber except 22LR so having said this - i have read the reasons for full length dies and from what i have read i dont think i should be using them but should be using just the neck sizing die- i dont even have just a neck sizing die - everything i have is full and i got all these thinking they were better - i have 220 swift- 204-223-22/250-243-and so on and pretty much one barrel in each caliber so as far as headspace is concerned wouldnt i be better off just using the neck sizer - what is your thoughts on this and what do you fellas use and why - my thinking is if i am only using the brass in one chamber then it should not need resizing and will shoot better but i gain this only from one read and it wasnt too in depth - so if this is right then new brass will not shoot as well as once fired in the same gun or am i missing something
