Thanks much. Wasn’t sure of the manufacturer.
It's been ages since I have loaded 308 for any of my guns. But I have tons of new Lapua brass and 155 scenars, 175SMKs, and 175 bergers. Does anyone have any good load data for 20" AiAx or At in 308?
Thanks
Thanks
"50 grs of whatever send it" snipers hide starting load crew
50 grs of whatever sounds pretty hot. I got a bunch of Varg and 4350 so ok...
Unless you are at 65k + psi you ain't reloading on the hide. Seriously... 40-44 gr of varget you will find something
You can probably do 50gr of H4350 and not get pressures with the 175s. But most likely it will fill to the neck and compress the load before hitting 50 grains. It's not the right powder for that cartridge/bulllet combo. I just put my 308 barrel back on and another hide member was just telling me, anything from 42-45 varget should work the the 170gr class of bullets. It's very forgiving and shoots very well going slow. But this is the Hide, load up 44-45gr and let it eat.
So pack it to the brim and mash the bullet right to the lands and bobs your uncle, got it!
Ok, seriously though, Ill start off with 43-44 and work up..
Sounds a little high to start with.
I recent looked at every thread I could find for loads in the 168gr range, IMR 4064 and Varget seems to shoot well for many people around 42gr.
I'd start be looking 41-45(maybe 46).
These are all the loads I found people using.
The "BNP" is Birmingham Nitro Proof mark (UK not AL)
the "CIP N" means that the proof testing complied with the CIP Normal standard
The Crossed swords and B are for Birmingham proof house (there's another one in London)
The 24 is for 2024 year
the X is the ID mark for the person that did the proof test..
I will start with 42 as recommended by you and a friend, and then do some loads in the upper spectrum, so low and high ish..
Thanks!
MPCT-3X. All of their reticles are great, pick your poison. Seems lots of guys are going back to the basics and choosing the simple MPCT-1X of late which I love for a hunting reticle/optic.

She’s running open class this month… like a fancy girl.
My bet is that somewhere between 41.5 - 43.5gr of Varget, IMR-4064, or Reloader 15 will shoot to the best of your barrels potential with 168-178gr bullets.
It is a great cartridge to load for.
I did a bunch of 175 Berger OTMs at 42 and 44, .05 off the lands. Gonna go take it out tomorrow and see how it goes.
It is a forgiving cartridge.
I'm picking up a 15 model PB AT this weekend and I'm wanting to add the NV bridge, but I'm wanting to make sure I can run the bridge with a 16.5" barrel and suppressor. Also, from my reading I'm seeing I need the high rail in order to line up with the nv rail, is that correct? The one I'm buying has the low rail installed. Obligatory pic of my hopefully new to me AT.

Yes you will need the high rail. I don't have a bridge but here is a 16.5 with suppressor. I believe it should be fine.
Measured my 20” barrel on my other AT to make sure I put the tape in the correct spot. The tape shows about 13.5” to end of the bridge which is about the same spot the spigot ends
Here’s also an 18” barrel for reference
16.5” wouldn’t be an issue
Knocked this piece of shit together out of scrap lumber, old dowels and rubber appliance feet.
It’s better than a bag full of barrel sleeves that weighs close to 30 pounds, but just barely.

Ok, little report for the load dev for the Ai 20" barrel.
Loading off the lands 0.05 with some twice shot and annealed Lapua brass, 175 Berger OTMs and 44gr of varget seems to do the magic. Getting 2650fps at 77deg, and a Stand Dev of 14.5, the accuracy is very nice.
I tried a 42gr load, it was not nearly as promising. The 44gr of varget does the job.
Cool that will be 50 bucks pm me for my venmo
Man after my own heart. You going to develop further or just leave it as is?
Im gonna go north of 44 just 0.3 so 44.3 and 44.6, and see how those loads go at long distance. At 44 there were no pressure signs, probably because I backed off the lands. I have had killer 260 and 6.5 loads that are magic at 100y and then go to shit at 1000. But after this I just want to shoot and not noodle anymore.
Some day if I get bored I will got down the 155 Scenar rabbit hole.

If you ever end up with some extra power pro 2000 powder load it in LC LR cases at max book load with a 178 hornady on top and it will do amazing things.
I always like the idea of doing .2 fine increments, that way if I can be bothered fine tuning more I can split the difference between them.
But I like your style, load development is shite. I enjoy reloading (so long as it's not at 1am the night before a match) but load development is not something I enjoy.
I’ve been running 44.1gr of Varget in LCLR cases with 210M primers with a COAL of 2.840 for 175SMK in my 24” 10 twist Bartlien factory AI barrel.
They run about 2750FPS or so @ 325’ ASL and are about 10 MRAD to 1K. (Right)
On the left is the 200gr 20X load I run in my 308 transgender AI. Runs about 2610FPS or 9.5 MRAD to 1K. COAL is 3.12. Lapua Palma/N150/205. Chamber has .170 free bore.
Bugholes is spinning me up a Brux 10 twist 30in heavy palma AT barrel with the same chamber for the 200 20X.
I figure they’ll be okay to load thru the port, but I’ll be fucked and probably have to fold the butt and pull the bolt if I ever have to eject a loaded round.
