No more than 100. You should know while fireforming if its an honest barrel, needs fine tuning or will shoot anything

No one fits all answer. If your an experienced BR shooter with many years tuning the same cartridge you will know in the first 100 or less. If its a new cartridge or combination to you it many take you quite a few rounds depending on your tuning skill. Tuning is a skill. It needs to be practiced and developed. Trying things until something works is not tuning, there should be a method behind the madness. I am more willing than ever to change components if things dont look right. All cartridges are capable of very good accuracy if the rifles built well. If you cant get it .3-.5 moa its not the cartridges fault. Bad barrels are RARE.
Per my data I'm 790 rounds into this thing, and it averages 1.16 MOA across all load development. I can get it to shoot some good groups with a certain bullet/powder combo, but the only downside is it's an anemic charge and ~200 FPS below where it should be.
If you can get it to shoot with certain bullet/powder combo order more of them!!! Its telling you what it likes if it shoot a certain bullet/powder. It may not be what you want or like. 200fps below ? I take accuracy over speed....
I feel your pain, my wife's 260 w/20" barrel drove me freaking nutz.I'm willing to accept that I'm not the best shooter, nor the best "tuner"; I certainly make no claim to be. That's half the reason why I lurk here so much; to learn from those that are more experienced. That said, I feel more than capable of consistently shooting at least a half minute, and routinely do so with multiple other rifles. I also haven't fired a factory round in ~15 years, so while I may not be David Tubb, it's not my first rodeo.
I want to be clear, I'm not dogging Lilja here; I think they make a good barrel. I will say this barrel coppers more than my other custom barrels, and just hasn't shown immediate "out of the box" accuracy like some other barrels I've had. If anything, you're probably right on the tuning piece; it wouldn't surprise me if this thing shot consistent .5 groups with the exact right load. If this were a .223 or something more economical to shoot, I'd invest more time and money into it. Unfortunately though, .260 isn't the cheapest thing to shoot; and it becomes less economical when you factor in only getting 4-6 loads before your brass is trashed (gas gun). So perhaps I agree; this likely isn't a bad barrel, it's just a picky barrel.
At some point though, when you're using all of the combinations that are supposed to work, and they just don't, you're left with a tough decision. Keep pouring time and money into it or cut your line and move on.
I'm choosing to cut the line.
If anyone here has a DPMS pattern AR10 and thinks they can get it to shoot, I'll make you a heck of a deal on a Lilja barrel; not even half way shot out!![]()
I know it's not what most are shooting on this forum; I've been on a gas-gun kick as of late while getting a few bolt projects rebarreled. That said, I was shooting an Aero Precision M5 AR10, chambered in .260, with a 20" Lilja tube on it. It's one of the prethreaded/chambered AR10 barrels Lilja sells on their website.
I ran H4350, Varget, RL17, and Ramshot Hunter through it. Also tried Sierra 123s, Lapua 123s, Berger 130s, 130 TMKs, 142 SMKs, and finally a 120 SMK that showed promise, but alas was only a .40 G7 BC, so what's the point. Trashed a fresh set of Lapua brass testing all of the above combos.
And before anyone says anything, I know AR10s are tough to get to shoot. That said, I've spared almost no expense on this one, and expect it to shoot better than some of the box stock sub $1k AR10s I've seen at the range before.
Lastly, I was shooting it at the same pace I would a bolt gun (i.e. slow fire). Cleaning was performed with BoreTech Carbon Remover, followed by BoreTech Eliminator using jags & nylon brushes.
Edit: I've seen some comments about reloading equipment used too; I tried sizing using a standard Redding FL sizer, and also used bushing dies as well with .002 neck tension. All seating was done using a Redding comp seater.
