Sorry guy's should have been more specific.
I am going for the neck size die only because
all brass has been shot once out of 1 particular bolt rifle.
All reloads will be shot out of same bolt rifle. Technically, I should only have to "size the neck" and by doing so, should be able to get more reloads out of my brass because I am not stressing the whole case length.
Kinda like in response to Heavies theory
Is my/our thinking correct ?
I just wanted to know if there was any preferences or advantages of Lee over Redding.
Obviously, we are new to reloading rifle and do have a friend who is VERY proficient at reloading including subsequent documentation

, but he had no opinion either way on the die
Will be doing a variety of loads/combinations followed by chrono and ladder test to find that "Golden Bullet" to go the distance.

The Dillon set up I got came with a full length die but because of the above method of thinking, I'm going with the neck size die only.
Nothing wrong Dillon Full length die, BNIB
As for my original post comments on case inside/outside 'that's what I heard"

and was looking for confirmation or rebuttal.
Does that change any of your replies ?
Thanks all
