Resurrecting this old thread with new info.
UPDATED.
It ain't the lube, folks its the powder / case combination.
I have to say don't use H335 for .303 British, at least with 150 Gr bullets.
I completely cleaned a set of cases that I'd never reloaded, & so hadn't lubed with anything. Then I loaded the H335 behind the Hornady 150 Gr spire points. The cases were only neck sized & no lube of any kind was used anywhere in any part of the process.
Charge weight was 38.3 Gr for an estimated velocity of 2550 FPS @ 10'.
I even went with a different brand of primer (Tula) in case there was something in there that was causing the issues.
Velocities were variable & there were several click. . . .BANGs in the loads.
Group sizes were terrible too 8" @ 200 yds with noticeable vertical stringing as the loads warmed up in the (now warm) chamber before firing. It happened 3 times with 3 strings, when I let the action cool completely the velocity & POI dropped back by the same 8".
It wasn't the rifle either, because another set of my handloads using IMR 3031 had none of these problems & circular 3 1/2" groups from the exact same bench/rifle/bullet/velocity/place , time & temperature combination.
