On my digital scale. Left, 23.0 middle 23.2 right 23.4. I've drone this many times, always with pretty much the same ratios. All weights shoot well for me, though 23.2 has the lowest extreme velocity spread.

One tin of H&N 23 gr .218 slugs weighed

Khornet,
Interesting results. Thanks for sharing the info. Have you tried analyzing accuracy after sizing them using a pellet gauge? Out of any particular tin, I find weight sizing has more of an influence on accuracy with pellets and diameter sizing has more of an influence on accuracy with slugs.

I've sorted a bunch of .22lr ammo with a rim thickness gauge but never got around to doing a test last summer. Thanks for the reminder, now I just need to wait for the snow to disappear in a few months.

Actually, I have used a rim size gauge with good results. And I started weighing the H&N slugs because I didn't have a good way to check diameter. Can't say for sure whether there is a performance difference, but I have seen tighter ES with 23.2 grains. From a previous lot. In a previous lot, 23.0 and 23.2 dominated, and 23.0 grouped tighter. I did not however compare the ES of the two.
Anyway hats off to H&N for such consistency, with 99% of a tin within 0.2 grains, and 100% within 0.4 grains.

With JSB I always feel the need to sort by weight as a tin of 15.9 will have a spread of weights from 15.3 - 16.4 grains. I stopped weighing H&Ns after I realized they have much better consistency in weight.

Yes, I own a K-Hornet. It's an old Savage Model 219 break-open single shot with a terrible trigger, and I think the bore is sized for .223 rather than .224 bullets, but it's a very cool cartridge. I shoot the H&N slugs from the pellet liner of a Power Plenum Impact MkII .22 700 mm barrel at 895-915 fps.
