Their barrels are outsourced. They used pacnor on the early m48's, not sure if I have one or not. Now they use shilen select barrels. I just screwed a new shilen on new bighorn action 20 min ago for a new rifle build. I bet it doesn't look like that 🤣. I did get a shipping label emailed to me...

The guy is super nice and helpful, but he just answers the phone. Hell, my rifle was shipped to a different facility that he wasn't even at to get worked on and test fired. All he can do is read a report. Thats why I have a feeling that there was a mixup of my rifle with a other. Something is...

Pacnor was the original barrel maker and now they use shilen select match barrels. I have/had shilens and never seen one tool marked like this one. Especially the issue with the chamber.

Kinda my thinkin...

I told him about it. He said he wished bore scopes were never invented 🤣. Pretty much it didn't matter what it looked like. Like stated above some ugly looking barrels still shoot good. But still.

Update: talked to nosler today. They are taking the rifle back in for another inspection. The guy was almost shocked sounding when I asked for a shipping label. Said he will have to get it approved since it will cost $250. Wth... he rambled on about it shooting so well for them and pretty much...

We'll see what happens tomorrow. I'll ask and see if there is a supervisor or upper management person I can speak to. I'll keep it posted.

Sorry guys. 143 HH's. I've yesterday to hit a flat primer or sticky bolt. 90gr of retumbo was slower that 85.5 so I beleive I'm at the point of no more return. 3650 fps has got to be a hot load. No need it pushing it harder than that. I cant make it even get close to their 1 moa guarantee with...

Yes. Back in earlier posts, I swapped to my nightforce nxs 3.5x15 with the same results.

I give up. I dont know what to try or do next. I'm just shy of 100 rounds through this rifle now with not a single group giving me any hope. Today I ran it up to 90gr. of retumbo to see if I could hit pressure signs... nothing. I used my magnetospeed on a 89.5 and 90gr load to see where I was...

86gr left 89.2 right. I see the ejector mark, but it's on every round I've fired including all the factory ammo. Zero sticky bolt lift.

Loaded 4 rounds in .3 increments from 88.3 - 89.2 to hit pressure to see how much further I had. Ran out to the farm and fired them. At 89.2, I still had 0 pressure signs. Case head and primer look the same at the 87gr charge. Ill load a few and see what groups look like pushed a little harder...

Just got back from the range. Imr 7828ssc gave interesting results. Retumbo was about the same except for the 88gr charge. 88 is book max but shows no sign of pressure. I may creep it up from there and see if things tighten up or itwas a fluke group. That is the best group I've fired out of the...

Got a bighorn TL3 on the way with a trigger tech diamond, grayboe Phoenix and bottom metal and 2 barrels. Ordered a 26" criterion shouldered prefit heavy sporter in 243ai with a 10 twist. I've got 12-20 weeks wait time so I had them send me a 24" heavy sporter 6x47 Lapua to burn up while I wait...

I will say, ADG makes some great looking brass! Just a pretty pic so we can have somethin positive in this thread 😆

I've got a couple more loads to try, hopefully this weekend before I go that route. I'm trying a lower charge of retumbo and giving IMR 7828 SSC a try for a little faster burn rate to see if that improves anything. I've shot off a bipod with my weibad prs bag for a rear support and I've shot off...

If it were closer to 1" I would be ok with chasing the right load. But over 2" just seems more like a problem elsewhere than a load. Maybe not. I will definitely keep the progress updated. I'll give 7828 and h1000 a shot and document results to send nosler. And my barrel looks close to the last...

The rifle has a 1 moa guarantee with their ammo. He told me they test all the 28 noslers with their 160gr factory ammo. Ill get a picture of the bore tomorrow and post it. I may still have a fired case with the ring tooling marks on it too before I sent it in.

I have h1000, and 7828 on the shelf to try next. Just need to find some time. I followed noslers data with 86-88gr retumbo. I'll back it down closer to your charge and see what the results are. I am using new adg brass but I will pay attention to the neck tension when I size them. I'll leave 1...
