Why on EARTH would you want to clean after every round, and 1.2" isn't anything to crow about. Not in a bolt action rifle anyway.
How well does your absolute best rifle group 10 rounds jorgeI?
How is that relevant to the shoot-clean-shoot question?
As to ten shot groups, it depends on the protocol I would think. Ten shots in a row I can tell you I would never do, now three, three shot groups, allowing to cool between each is something I have done and in that case, probably under half MOA.
It is of no relevance to your shoot-clean-shoot question.
Use any protocol you'd like at 100 yards, letting it cool will help. Just 10 shots at 100 yards on the same target. A 10 shot group under 1/2 MOA is quite impressive from a hunting rifle.
Doing it with a clean barrel, essentially 10 cold bore shots, is a twist on it if you must tie the shoot-clean-shoot in.....
