How were the groups with the 165tgk? Mine didn’t seem to care for them
 
What COAL did you use. Hornady listing 3.070 for 162-166. I did that on first round and it looks wildly too deep. I backed it off to have the bottom of bullet just below the shoulder/body junction.
18” barrel

What is your load
Thanks
73gr n570, Peterson brass, cci250, 2.5935 cbto. Seems to be hanging around 2850fps out of my 18”.

Obviously work up to the 73gr. I started around 69gr and found great accuracy all the way up to 73.5.

900 (3 shot) and 1000 (4 shot) yard groups attached.

How’s the ADG brass to those pressures? I’m using Petersen which seems to be holding up good. Pushing 3050 from a 22” barrel (69g n560) slight extractor smear. Heavy bolt at anything over 3050 on this gun. Hornady brass primer pockets are done after 1 firing 👎🏻

For reference Hornady match 180 shoots 2860

I haven’t tried the ADG with the n570 load. Was using h1000 for that and didn’t push it at all. The Peterson is holding up great
