Another thing to think about is that the 6.13 and 6.23 wide bore barrels are more forgiving to bb defects. If you had a 6.00, or 6.01 for that matter, any slight bb defect could fling your shot to who-knows-where because the defect would be touching the sides of the barrel, guaranteed.
Whereas the 6.13 and 6.23 would allow for some room between the defect and the barrel.
Either way, a defect would throw your shot off where it's supposed to land, but in theory the wide bores would be more forgiving to it.
Take me for example… I use a 6.10 and those dang white .43s (higher percentage of defect per 100…) And I still manage to hit 10/10 at 230 feet
