I now believe that the explanation for why my 22WMR groups started to open up so much was more do to with carbon fouling. Micro-groove rifling and excessive carbon build up don't equate to accuracy.

After soaking 24hrs in Hoppe's No. 9 and 2 more 20 passes w/bronze brush followed by soaked patches, I'm still pulling black patches. Geesh! How much carbon can fit into those micro grooves?!

I suggest you not strip the bore to spotless.
Dry it and go try it now to see if accuracy is acceptable.
If not, clean a bit more and retry. Repeat as necessary.
Ime a totally stripped bore isnt accurate anyway.

Not a bad suggestion.

So this is what I got out of my Savage FVSS yesterday (Hornady V-Max, Hawke 4-16 Sidewinder scope) at 100m (110yds.)
Factoring in the difference between metric/imperial, two of the groups are just a shade under 1moa, the other two about 1.25moa.
Pretty happy with the day.

Last week I had time to get to the range. After zeroing in, surprisingly, it was the CCI 40G FMJ HP Maxi-Mags that held the tightest group. Slightly over 1.25" at 100 yards. This was compared to CCI/Hornady's
.30 V-MAX and their .45g Critical Defense rounds.

B, it's not brand or type that produces the best results with 22wmr ammo.
I've tried them all across a chronograph to compare the results.
50 shots at a session to understand what is occurring.
Our results are directly related to the quality of the cartridges as they come off the assembly line.
If you are sold a box that was produced during a run where the tolerances were tight
and the primer amounts were metered in correctly and the bullets weren't beat to heck before seating
you can produce some very tight trajectories. The problem is getting your hands on a good box.
None of the makers of 22wmr try to maintain that level of quality.
Not CCI, not Winchester, not Aguila, not Armscor, not Sellier and Bellot and most definitely not RWS.
Federal, Hornady, Remington, Fiocchi and Norma are all relabeled CCI.
Browning is relabeled Winchester.
For all of them, it's just hunting ammo.
If you miss a shot, so what? Get closer for the next shot.

Yeah, I get that. But, opening up to 6" is even beyond sloppy manufacturing tolerances for a hunting cartridge. I do expect to be able to put rounds from a bench under 2" at 100 yards. If not, I might as well buy a federal tax stamp and lobby my game commission to allow full auto.

I hear ya' B.
I have tried one dot one shot targets at 50 and 100 yards with 22wmr.
The results were less than satisfactory.
About half the shots hit close enough to center to make me happy,
the other half would wander off due to cartridge defects.
Center of critter covers a fairly large area.
Center of bullseye, that's a whole different story.
