The howa barrel is not a custom nor premium one. I have had a few, in the 20". That being said they do shoot pretty well. I think for the grendel ones I did a JB bore shine first before shooting, then clean that out well, but you can just do a clean first to get any gunk out, then your cleaning series.
I usually did a short break in for them. Like you said, 5-10 of shoot 1, clean 1, then maybe a 3-group and clean. Up to somewhere 10-20 rounds, it gives you the ability to break it in.
I use normally some factory brand, for 6Arc either of the 105 or 108 hornady would do fine, whatever is the better deal for you.
