Ok I'm real late to the part but here is my advice.
If you follow it you will find good to great groups if you dont well you get more of what you already got.
First your barrels are too shelf, your handloading practices are the issue.
Fix number one. Grab some arcomp
Fix number two get a chronograph
Fix number three get the hornady coal measuring tools
Fix number four get a micro meter seating die like a foster or Redding.
Take whatever bullet you want and start it 20 thousands off the lands OR just short enough to properly run from your mags.
Pick a starting load and do one round per .2 tenth charge and work up too listed book max, run them over the chronograph and you will see a charge that stands out velocity wise that says hey your now in high pressure, it will be out of place for the deviation standard from one charge to the next. That's your rifles max charge.
Now go back and look at the lower charges, you will see some that doesnt have much change per charge weight diffrence. Take those loads and load 10 of each. Go back and shoot them over the chronograph. Take the load that gives you the tightest sd/es numbers.
Now go back and load 10 more just like them and load 5 more at a step down 5 thousands at a time till your 20 thousands shorter then your first 10. Shoot those over the chronograph for groups.
In those sets of rounds your will find your load and seating depth and the groups you are looking for.
There is no free lunches, you have to put in the work with the proper tools and small changes too get a great load.
Some more tips. It's a ar15 not a bolt action, you cant limp wrist it you have to hold the gun firm and drive it.
I didnt see anything about the gun itself but it could be you need a better trigger, maybe a better setup at the bench aka better bags and no bipod.
Hope this helps. A5BLASTER out.
