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 the high rail for the NV mount

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.

I’ll throw a tape on mine quick for you and edit this on the barrel length

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

I ran that setup on my AT-LE for a while, you'll be fine.

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.

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.

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.

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.
