This is my advise to you.
Each manufacturer uses a different lubricant on their bullets, some also use less like CCI or Aguila, and some use a lot like RWS. So what I do per my dad's instructions almost 30 yrs ago, is a quick clean of the barrel after each brand of ammo.
Then I do 5 shots to foul/grease the barrel, and then shoot a group of five. Otherwise you'll get mixed results.
I would do this and test them all over again, just my $0.02 and hope it helps.
You should be able to group 5 or 10 shots inside a nickel or dime, of at least one type of ammo.
Here is a group of my 10/22 @ 50m with Aguila Ammo, and with the horrible factory trigger. Two outside the nickel when I measured it, flyers? Maybe, or might been me.
