AR-10 double grouping?

[Klong]

I know it's only 2 groups, but they're similar shaped, at least to my thinking. These are 2 five shot groups fired today with an Aero Precision M5 with a no- name 6.5 CM barrel. First 5 are the higher ones shot at 100 yards, next five are lower and were fired at 200 yards. They appear to be similar shaped, seeming to string a little diagonally down/ right.

Do you think this is a shooter issue (I'm not an expert in ARs by any means), or is this a barrel/receiver fit problem? Or is it just a cheap azz barrel issue? This barrel is probably going to be pulled eventually, but I'd like to know some possible causes for what I'm seeing.

Thanks folks

Did you solve this?

I am leaning toward this being a shooter issue with maybe a little bit of less than optimum load. This first picture here is the same load as before, but this time I had the rifle and rest on an actual bench. A wobbly bench, but still a bench lol. Yes, that is still 5 shots.



The earlier groups were fired with the front rest and rear bag mounted on my trucks hard tonneau cover. You'd think that would be better, but maybe it was just a little too high or I wasn't able to get nice and square behind the rifle.

This second picture is a different load. These were 107 grain smk pushed by 40 grains of Varget. A motley combo I'm sure, but I'm essentially just burning up remnants of stuff until my "gooder " barrel comes.



So really, for a no name barrel and bolt combo, it performs beyond what I was expecting. I think the original owner said it was a Delta Team Tactical barrel, which from a quick Google search gives the impression that they're one step up from hot garbage.

I'm hoping the new X- Caliber barrel and headspaced HP bolt can do a little better. I think from what this one has shown so far though is that I probably need to improve some as well though.
