None of them.

If the ammos you're using aren't giving you the results you want, there's only one thing to do that will help. Get better quality ammo. Of course a poor barrel can't shoot any ammo well.
 
Case volume is more important. Fire form your brass, neck size it and then sort your brass by volume.

As mentioned, if your barrel is garbage it's a waste of time.

**Haha nevermind. Just seeing that this is in the rimfire forum. Buying quality ammo is about the best you can do.
 
Open the box, load ammo and fire. You can sort out everything. But there are so many factors. Weight wont mean much. Because you don't know if it is the brass, the bullet or the powder charge. Making the difference in weight between each round.

Then youll see there can be variation between lots of ammo. And just because something has simular mv, may have different impacts.

Rimfire ammo is dice rolls. Even higher end ammo has it flaws.

I kind of knew that yet I was, naively, hoping to get some straight answers to a straight question... So far, as any reasonable person would expect, opinions and remotely related opinions... Still, I hope to hear from someone who actually tried the 3 methods and how value one above the other. Chances are low and I'm not holding my breath yet... I do hope to hear from someone who actually did try these methods and is willing to share their first hand experience with these. Why? Well, I'm planning my retirement. The budget will not allow me to shoot anything I want anytime I want... 22Lr can stretch this budget a lt... Now, I have access to tools to craft any die I want.I can make adaptors to measure anything you can imagine. I own tools to measure precisely yet, without proper adaptors these may be next to useless...
To add to picture... I do have extensive experience with reloading for 30-30 , 3006, and 45-70. My 23Lr experience is limited to plinking. I still have enough supplies for a small war or a large revolution... but my world will be soon turned over... I dream of punching paper... while chewing on a moose burger..For the moose, my loads can do that. For 22 fun, I want to raise above the basics.

None of the above matter

If you want to up your game AND the barrel/chamber has the potential to perform, start looking at higher grades of true match ammo.

SK rifle match or long range match. Eley equivalents. These are entry points. Test to make sure the rifle can actually shoot better.

Then look at Lapua, higher grades of Eley (match and Tenex) and RWS (best grades).

Nothing you do physically to sort the ammo will help. The lower the price, the lower the performance.

From everything I have read, short of keeping one occupied, these activities will have little to no effect on accuracy or precision. Tuners work... on some barrels, rifles, but in most situations, they don't do much either.

From time to time, I shoot 10 shot sub MOA groups with TAC-22. Sometimes they are closer to 2"; same goes for various, more expensive Eley, RWS ammo. Could be me, could be wind etc. The old Go-to; CCI STD shoots OK but not as well as TAC-22.
 
This is something NOBODY talks about. The ‘back story’ is when I first started looking to buy super high end semi custom beautiful rimfire rifles like Cooper and Kimbers I would carefully examine the included test targets that came in the box.
What jumped out at me was the statement that every round was HAND FED into the chamber, NOT from the magazine, hmmm.
How a magazine presents a round and how its trip to the chamber deforms a bullet has consequences on ultimate accuracy…potentially significantly much more than rim thickness measurements etc etc etc……
I won’t bore you with all the tests I've done and I don’t want to deprive shooters from the ‘joys of experimenting’ so go ahead and play. Let me just say from experience that to go from starting out plinking to winning national championships is a long road…. along with at least 100 things you must do and pay attention to and rim thickness and bullet weighing isn’t even on the list. I don’t mean to burst any bubbles but the older guys here know what Im talking about. Cheers…
 
Thanks for the eye opener! I've seen many rounds deformed when feeding from the magazine. As a plinker, I didn't pay much attention to it. Looking forward to be more of a paper puncher, I'll be paying much more attention to the issue.
 
Good ammo shoots well in good barrels. Ammo that's inconsistent is always inconsistent.

An important thing to keep in mind is that not all lots of match ammo are equally consistent throughout. In other words, sometimes some boxes are better than others.

This can cause different results with the same lot from one day to the next. It can also cause two equal barrels/shooters to get different results with the same ammo. This potential problem is more obvious the further the target distance.
 
If you want to spend time 'looking at ammo', here's some info to consider. The whole thread here is interesting but if you go to Post #54 and read from there, some interesting tests are revealed.

I'd like to thank everybody for their input and especially for the constructive comments. I'm planning to retire from this thread for now and possibly revive it, in the future, once I have, personally obtained, hard data to pressent.
At the moment, I don't have time nor place to experiment. I do have time to prepare for the experiments.
My theory, at the moment is;
Mathematitian in me tells me that sortinh may result in some groups being exceptionally good and some exceptionaly bad.
Phisicist in me tells me that unless I direct every cartridge and match the rim size, bullet weight, shape and concentricity and shape and powder weight, and primer distributon and match it to the barrel harmonics, it's pointless.
Experienced centerfire reloader tells me that uniformity and proper headspace is the ticket.
An old fart tells me.... The proof is in the pudding.
