I have always FL resized new brass before using it the first time. I was wondering if this was necesary or could I just neck size? It will be shot in a bolt action rifle. Your thoughts?

For new brass, I only neck size. And I've never had any problems chambering rounds.

I've got a couple of lyman M dies...just a mandrel in a die. Don't even have to lube virgin cases...just plunge them onto the mandrel and withdraw the case.....it will have a nice perfectly round case mouth/neck with about .003" grip. Runnout winds up being quite good doing just this....after the first firing of the brass is when I do more work to keep the brass a bit more uniform.

You can set your die to FL size and it will only neck size new cases anyway. So just neck size and straighten up the necks for the first firing.

Is FL sizing "necessary"? No. But, why not? It would make sure it's all the same, it's easy to do and you already have the tool (die) mounted to do it. ??

I have been reloading extensively since 1973. I shoot 3000 plus rounds per year, with rifles of all sizes, I have never resized new brass, see no need to, and don't intend to start. I shoot for greatest accuracy and this is usually with once fired brass, not always, depends on the barrel and chamber. Good shooting.

With one exception that I don't need to go into, I never resize new brass. The most I do is chamfer the case mouths.

That's why I only buy two die sets. The F/L die so adjusted gets the job done.
The reason for doing the neck sizing on new brass is that the cases don't have perfect necks, some are deformed more that others. By doing the neck size on new brass, you have consistent neck tension on seated bullets with all of the brass from the git-go.

Sometimes you have to size or clean up new brass. The necks of factory Rem and Win brass is often dinged and out of round. I will run them just far enough up into the die to get the expander ball to round out the case neck. Otherwise this will vary your seating tension. More expensive brass (Lapua, Nosler, Norma) does not requite this step, and is normally ready to load.

I also chamfer the inside of the neck, since most new brass has a slight burr. This will keep from shaving the bullet when seating.
