We both got higher velocities with N570, I think my friend was getting around 3050 through a 32" Bartein with no pressure signs, but the temp sensitivity was a deal killer for both of us.
I think we were in squad 3 this year and by my count I shot significantly better except the scoring fiasco...
I'd be careful with N570, I shot it for 2 years, but found it was extremely temp sensitive. So did my friend who was shooting it also during that time. We were shooting ELR rifles with 30-32" barrels, Lapua Cases, Fed 215M primers, Berger 245 EOLs, and 81.0-83.0 grains of N 570. At the 2023...
I used 16 lbs. of the stuff when H4350 was really hard to get. My load with Hornady brass, Hornady 140 ELDM, CCI BR2, 41.8 grs. of IMR 4451. gave around 2700fps in a 24" Bartlein and very good SD. It is temp stable. No cons that i can think of its pretty good in 6.5CM.
Most of my precision rifle scopes have sunshades and Aadland caps or Tenebraex caps (no I don't use the ARDs). Besides the benefits in the few situations that you would need a sunshade, they do help protect the objective threads, and I have shot mateches in the rain where they kept my objective...
Every ring I can think of, Leupold, Seekins, Vortex, Nightforce, Spuhr, ARC, Badger, TPS, etc. all have some markings somewhere indicating the mfr. If there are no markings anywhere perhaps you have chinese made airsoft rings?
The CDG action offers two bolt handle configurations. The conventional configuration has a fixed bolt handle and primary extraction is by the conventional way of opening the bolt bears on a camming surface that provides primary extraction. The pivoting bolt handle configuration has a pivoting...
Semi auto rifles are almost never as accurate as bolt guns. Particularly large frame ARs are harder to get to run well and shoot accurately compared to a bolt gun. Plus bolt guns are easier to maintain and cleaner (no dirty direct impingement gas systems). The advantage of a semi auto in a...
There are many makers of barrel vises, this is the one that I have, the Short Action Customs (SAC) modular barrel vise:

It's on the upper end of the price range, but the less expensive SAC Bravo barrel vise is also excellent.

If you can get and use a torque wrench, barrel vise, and action wrench, you can put the pieces together yourself. Start buy buying a modern action that gunsmiths make shouldered prefit barrels for. They make them for the actions that reliably hold tolerances so tight that the gunsmith doesn't...
I just got my Carbon Grey mount and it's high quality and works well. For the price it's an excellent value and includes an Arca clamp. Shipping was super quick, I ordered it on Tuesday and got it today, 2 days later.
For ARs I use the Tactical Brass Recovery (TBR) catcher and it's expensive but works great. For my bolt gun in matches I use the MPA brass catcher which also works very well, with my ARC Archimedes action, I just need to make sure to run the bolt firmly so the cases get thrown into the catcher...
For a rifle barrel, copper and nickel anti seize will work equally well, nickel is a premium anti seize suitable for extremely high temperatures, but for what we're using them for, they both are fine.
I use nickel anti seize, but Aeroshell 64 would probably work just fine. The AE is a conventional barrel torqued onto the receiver and I would use anti seize (or your Aeroshell 64) on the barrel threads
Did you adjust the ocular properly? Not doing that right will give you a blurry reticle and blurry image

I don't have one but my friend who has the 4-16, 5-25, and 7-35 ATACR has let me...
It looks like corrosion but until you swab it out with solvent and a penetrating oil like Eezox or Kroil, it's hard to know for certain. However, I've seen barrels that looked bad inside that shot very well, so I'd probably clean it with solvent then go shoot it...
You can get profit Tikka barrels from PVA. Other than that, I agree that in todays world it doesn't make sense to get any action that doesn't have profit barrels available.
In this megathread, @Frank Green talked a little about having his barrels coming back for issues where BT products might have something to do with it.
