In the ballpark is pretty broad for packet brass, some of my Remington brass necks look like someone had at them with a pair of pliers before packing them.

I am not too concerned about them until I have fired them once, as long as they are within spec and without any major deformations that firing won't correct. Full-length sizing new brass before firing just works the case for no practical benefit. It's similar to neck turning before they are fireformed – a pleasant way to pass time but ultimately unnecessary.

Once they are fireformed to one of my target rifles, I begin batching and then only neck size, with the occasional body die bump and annealing every ten to fifteen reloads. I have never had to full-length size new brass of any brand to get it to chamber.

I don't think neck tension is as significant an issue when seating close to the lands. Unless there is a thickness issue (I often trim when necking cases down), I leave the turning tools on the shelf. I personally aim to see return for my time spent; if I don't perceive a benefit, I don't invest the time. I ceased primer pocket uniforming and deburring, as well as mandatory neck turning after dedicated load development revealed no advantage for me, and I haven't had any issues—but that's just my experience, not a universal truth.

For hunting loads, I definitely wouldn't bother.

Just my humble opinions.

Many shooters and reloaders debate whether it's essential to resize new brass right out of the box. Despite differing views, most concede that for precision and competitive shooting, additional steps may be useful. Here's a closer look at some perspectives:

• Precision Shooting: Competitors often full-length resize and meticulously trim their new brass, seeking consistency and accuracy.
• Hunting: Hunters, on the other hand, might skip these steps if they don't affect performance noticeably.
• Case Life: Properly sizing brass can extend its usability by preventing cracks and deformation, particularly for higher-pressure rounds.

Ultimately, the choice depends on your specific needs and objectives. While some find a rigorous calibration process indispensable, others prefer a simpler approach, relying on fireforming to shape their brass. Whether you opt for full-length sizing, neck sizing, or no sizing at all, understanding the nuances will help you make an informed decision.
