German Salazar and many others have researched this topic. The link below is a search on his site for .308 and many articles popped up. IMHO, and others, to keep a .308 bullet trans-sonic at 1K is very difficult, and with a 22" tube even more so, at safe pressures. I'm not talking a couple shots at unknown size targets but successful competitive shooting.

It is not difficult with RL17.
To do it with extreme accuracy using a very stable powder like H3450 or Varget then yes.

With a 22" bbl I can almost get to 2600 fps with the 208 gr amax over RL17 at 2.95 col and that is a chronographed safe load in my rifle tested in 95dF heat.

Its a hot load, but no brass flow and the primers look good. That is running right at 60-62k

Back off 1-1.5 gr and you are still running 2500 FPS but at about 50k and 2500 FPS with the 208 Amax is super sonic out to 1200 yards.

The tricks are you need a long enough throat and magazine to run at at 2.95" or longer, use Win brass (2 gr more cap than Lapua) and its best if its fire formed and neck sized.

Palma 1000 yd matches are shot using 155 gr bullets.

That is for international competition. I could be mistaken but the stateside matches are not putting limits on the bullet weight.

1K is easily done with your rifle, so don't get down hearing people doubt it. I'm shooting a 12 bvss .308 and my choice load for OVER 600 meters has recently been Hornady 180gr sst's with 2000MR powder. Very accurate, and has been very reliable.

I tried both Black Hills 175 and Hornady 178 HPBT (not the Amax's). The black hills did great out to 900, but started to really have problems at 1000. The Hornady 178's however did very well all the way out to 1030.

Excellent! The farthest I have been able to shoot so far has been 1250 and the Hornady 180 sst's did awesome. I may need to try the 178's just to check them out.
