This is extremely non scientific and purely anecdotal but I thought it was interesting. I still have one rifle threaded 5/8” before it gets cut shorter and threaded 1/2” (just for consistency across my rifles) so some of my 1/2” threaded guns have secondary adapters on them to jive with the 5/8” HUB adapters.

Rifle is a stock T3X 22-250, 1-8”, cut to 19”. Scope is a 3–15 SWFA in Hawkins LR hybrid rings.

I fired 2 groups, one with a Resilient Jolene S with the 5/8” Hub adapter and the secondary 1/2 to 5/8” adapter on the rifle. Prone off a bipod with a rear bag. All shots felt pretty solid. Resulting group was 1.3” with a large amount of that being vertical stringing.

Next group was 7 rounds from the same position but the Jolene S was swapped out for my Polonium 30 with a Kaw valley precision 1/2-28” HUB adapter and the secondary adapter removed.

Resulting group was 7 in just over 1/2” with 6 being almost in the same hole.

Now, I have had suspicions about using secondary adapters for a little while and while they may not be well founded for others, stacking tolerances on this particular rifle seems to be problematic. Of course there could also be some harmonic differences with the 2 cans but the Jolene S appears to not be the issue on a couple other rifles that hammer with it, without the use of a 1/2 to 5/8” adapter.

Anyhow, I’m sure this probably is just a sample of one but thought some may find it interesting. I will repeat the test with the Jolene S with a 1/2” HUB adapter to eliminate one more factor next i shoot.

I’ve wondered the same about that. Every time I’ve bought a new 1/2x28 HUB I’ve thought about the savings of just getting an adapter. I guess by replacing the HUB it eliminates that possibility. I am aware that many are using the adapters and shooting better than I do with out them so it may or may not be a thing? The proof is in the pudding with your rifle though. Sample of one or not. Thanks.

I'd look at the difference from can to can before jumping to the adapter. How's it shoot bare muzzle?

Some POI inconsistencies this winter led me to bring suspect of the adapter and they did seem to go away when I stopped using it, but I agree the cans could be the bigger factor.

You know, I’m not sure I have ever fired a group with this rifle and ammo without a can. That would be a good control.
