Like Vascar said you are probably somewhat limited by the barrel itself.
That being said the lighter bullets would I think have the best chance of some accuracy.
I know factory loads are expensive these days but do you have at least one box of factory you can shoot? that would help break in plus at least factory stuff should work and give you an idea of performance. Not perfect but it's a start.
I like these light wt bullets.
100 gr Nosler BT or Hornady eld-whatevers.
95 gr Hornady Vmax.
90 gr TNT (speer).
107 Sierra SMK.
Do you have a chronograph?
For powders the good ones for lighter bullets are H335, 8208 xbr, and TAC. Others I'm sure but these work well.
For a rack-grade barrel don't expect any good groups until 50-100 rounds down the tube. So you might still be in that initial period.
You want to do a load ladder of 1 powder, 1 bullet and various weights based on Mfr or published data, to look for a good grouping.
Example: 95 gr Vmax and H335, from the book, 28.0 is min I would start maybe 29.0, 29.3, 29.6, 29.9, 30.2, 30.5, 30.8, 31.1 (31.2 is max but watch your own gun's response).
First set, use 1-shot per load, so you can get a graph of how your powder jug and bullet work in your barrel (each barrel is unique, and powders differ from lot# to lot#, so load data is just a guide).
Then for second round, Use 3 or 4-shot groups at each load.
I would also use just a regular carbine buffer weight, start simple and work up from there.
If the line graph of the first ladder looks weird or none of the load-sets group, then you can get into troubleshooting.
I will help you with charting but without a chrono it's a lot of shooting in the dark so to speak...
I've got grandkids so I'm with you...
