I have tried it in 06 w/147 FMJ BT's, and it worked well. In 308 I have tried its near identical burning rate twin over at Accurate Arms, in the form of AA2460, and it worked very well with great velocity and load density. I just looked over my load/chrono data, and the exact same charge of H335 and AA2460 gave almost the exact same velocity results from the same 06 mentioned above.
Not that I can confirm this, but it is said that H335 is very close (maybe the same) as some lots of non canister WCC844, so this would make it at least a good choice for the .308 to easilly duplicate M80 ball loads, and still pretty good for those 165's. Looking at the Hodgdon data, the velocity to propellant weight looks good, as does the density. I think you will find H335 nice in .308, and for sure in .223 if that matters.
Good luck!
