I am testing a theory of just pushing a dry patch through the barrel a couple times rather than doing a full cleaning with solvent that strips All the carbon and copper out that then requires 5 to 10 fouling shots.
Dan Flowers, The Ballistic Edge, (after a successful military career) did and published a study on cleaning levels, and leaving fouling in a barrel, relative to sniper accuracy in both military and police weapons systems.
A number of people have followed his study lines, and boresnaking only, fired 8-10,000 762 rounds with no appreciable loss of accuracy in combat zones and competitions, until the barrel wear rendered it unserviceable.
Battlelab at Ft. Benning also did a comparable study, as did a contractor group from building 4.
The results were comparable in each study, however, all are barrel dependent on the quality of the barrel to begin with. Good barrel, good result, mediocre barrel, mediocre results, crap barrel, crap results.
Any barrel requiring 5-10 rounds to settle after cleaning, was considered a below sub-standard barrel, and would be replaced asap.
Combat zone weapons during a tour, that could not be immediately replaced, had acceptable fouling levels that held work standards until tours end, when they were replaced.
Your theory has been examined before and found very barrel quality dependent with equally varied results, great barrel, great results, shit barrel, shit result.
100 Hide posting answers will vary depending on barrel quality.

Every generation it seems has to rediscover fire, and recreate the wheel.
