#4 looks pretty good. I like to test at 200 but I have a good spot with no wind. It looks like you’re definitely getting there. Just a fussy setup but really worth it. I bet you get a few guys drooling over that thing at a range ( I’d be one) Will be cool to see it finally finished and dialed in

Scrap the 5 shot groups. They tell you nothing and are just tons of extra wear on that little barrel. 3 shots as fast as you can shoot them then let the barrel cool. Any other way introduces way too much noise and your tests are just a waste of components. Any guessing on what is working is just that i assure you. If you do that same test, 3 shot groups without pauses in your group and cooling between we will be able to pick one out for you.
Not sure what your hunting range is but hammer bullets are about the easiest tuning bullet I’ve ever came across. Excellent performance on game. Definitely recommend you to try and don’t go under recommended twist. The absolutes will give you 2-300 fps gains.

Try some different bullets 175 Sierra's both SMK and TMK. you may find it's your bullets the rifle don't like. Also so try 42.0 IMR-4064, with the 175's. Load to 2.820 OAL. Then try seating depth from there.
OP, I understand the desire to make the best of a beautiful rifle, something we all try to do.
But, respectfully, you are chasing your tail. Many good benchrest competitive shooters have commented on this thread. They know what they are talking about, I also played the game for nearly 20 years and have been building and shooting hunting rifles for much longer. Your rifle is a very nice hunting rifle, not a target rifle. Don't use a screwdriver to hammer in a nail. If you want to shoot groups your time will be much more enjoyable with a purpose built rifle.. I've been down your road many many times. My observation is simply an effort to keep you sane. Enjoy your gorgeous rifle for what it is.

YUP!
5 shot groups are great, but for a hunting weight barrel I would go with 3 shots. Be careful trying to get benchrest quality groups out of a pencil barreled rifle. Before long, your barrel is going to be shot out.
The groups you've posted are more than adequate for a 308 hunting rifle. If you can't get it killed with 3 shots of a 308, u may be better off running away rather than sticking around

OP, forgive me if this is covered already in responses to your thread…how many rounds do you have through the PAC NOR barrel?
What is your bore cleaning frequency? Do you use a bronze brush when you clean? What is your process to stay ahead of hard carbon build up in the first few inches ahead of the throat/freebore? This carbon I’m referring to is not simple powder fouling.
In most barrels I have found it necessary to carefully use Iosso bore cleaning paste every 150 rounds to remove that glazed hard carbon from the end of the throat to approx 5-6” past. This is necessary for optimal accuracy. Liquid carbon solvents will not remove the accuracy robbing hard ass glazed carbon from that area. If not managed properly this carbon will ruin accuracy and cause a lot of frustration. Groups will go to crap quickly along with elevated pressures if one does not stay ahead of it and prevent this hard carbon build up. Cleaning with BoreTech C4 and a good Pro Shot or Dewey bronze brush immediately after shooting while the barrel is still warm also helps prevent that hard carbon.
All I shared above is just my experience. YMMV…and carbon build up may not be an issue at all for you at this point in time. A Teslong bore scope is a cost effective tool for the sole purpose of keeping tabs on whether our bore maintenance/cleaning is effective or could use some improvement.
Also, factory ammo will probably not perform with the consistency that you may desire. None of it will perform as consistently as well made hand loaded ammo.
My apologies if the above has been covered by others or if I’m preaching to the choir …I have no time to read all 8 pages at present.
Hope some of that helps you or someone else.

I actually just bought a teslong scope and checked it out. I clean with butches bore shine and pro shot rod, bore guide, and caliber specific jags. What I usually do is wet patch until clean then run a bronze brush down it about 5-10 times and wet patch again until clean. I do that cycle until patches are pretty much clean after brushing. I also used some sweets and cr10 during fisrt couple hundred rounds and never got any copper out so I stopped using it. I haven’t run into pressure and am getting good velocities. The barrel has 470 rounds on it now. Here is a couple pics of the throat.

Man you already got firecracking in there. Thats a lot of rounds
Is that more than normal for the round count?
Remember this statement.
