Just curious if it is better to run fired brass through a full length resize dye or use a neck sizer dye,I’m not positive but I thought I heard someone say it’s better to use a neck sizer only,thank you for any and all reply’s

I prefer to full length resize brass for a hunting rifle. I don’t want to have any issues chambering the round in the field is how I think about it. I have played around with other methods and haven’t noticed any difference in accuracy. I would be curious to hear others thoughts on the difference in accuracy.

If the brass is from your rifle and will only be used in the rifle it was shot in your ok to neck size. Otherwise your using fireformed brass in a rifle that it wasn’t formed in and you could have chambering issues. I full length size everything and haven’t had any issues.

The brass will be once fired from the riffle in question,does it change P O I from neck size to full length sizing ? Or help in accuracy ?

The biggest benefit in neck sizing, is less working of the cases, which improves case life. I generally run the cases through a neck die, until they no longer chamber without resistance, then I bump the shoulder back, and resume neck sizing. In any case, I chamber the cases for my hunting loads after sizing, to make sure that they chamber easily, before loading them.

Some are of the opinion that NK sized brass better “fits” the chamber than FL sized and consequently is more “accurate/consistent” but IME, that is not the case. The main benefit of NK sizing only is that it likely improves the service life of the brass. And, sooner or later, NK sized brass will need to be FL sized. Any change made during brass prep can change downrange results which means that NK sized brass may not give the same POI as FL sized brass.

I agree.

As an aside, I just sent fired cases to Whidden Gun Works for a custom FL sizing die. These dies will size the case minimally. Trouble is, you should have your own reamer so that the next barrel can use the same die.
