Could age of ammo be an issue? The newest ammo I have is probably 5 years old. I should try some new stuff and see.

With the cartridges in the tray a quick look will show non-conforming bullets
seated more and less than the average. Rolling a cartridge on a flat surface
will show tip wobble about the axis of rotation. Not something you want to see.
For less than 50 yard usage the effects are minimal,
at 200 yards poi can be 3 to 5 inches from poa.
And there is that.

I shot some old ammo last year bought during the rf ammo depression and mine was fine. Luck of the accuracy draw with CCI manufactured ammo IMO.

To get optimal accuracy out of my 22LR ammo, I weight sort to +/- .05 grains. This stops my OH **** sudden flyers for me. Yesterday I shot a 160 shot prone F-Class 22LR rifle match using SK Pistol Match ammo. Out of the 100 shot initial portion of the match at 50 yards, I dropped only one point with 78 X's. The dropped point was due to a bad wind call on my part. The target used was the NRA A50 target. This was all with weight sorted.

Due to this practice, I have started weighing my 17HMR rounds. I shoot Hornady 17 grain V-Max exclusively. The weight variations are LARGE, but I was able to get enough for a match out of a box or 2 that meet the +/- .05 grain standard to 22's. This coming week I will take my Anschutz 1717 to the range and see what I can do in the 50 yard IBS target. Also I'll check for split necks.

I hope weight sorting works for you.
I've attempted it with 22lr, 22wmr and 17hmr with no improvement to the results. 500 rounds each time.
No, let me amend that, it let me pull 22lr with no powder in the cartridges from bulk Federal.
Shooting outdoors off a bench with a barrel block rig, it didn't help my results.
Still had mv spread, still had strays, good luck.
