I never did any Berger's with my Tikka CTR...Nosler's and Hornady's only. 143's, 147's and some 129 LRAB's.
FWIW, it may not be of any use to you....all my best loads(groups) with the H-1000, for every weight of bullet I tested was right up against the max load in the manuals ! It was 59.9 and 60.1 grains.
CAVEAT...I worked up to every final load I used, looking for pressure signs along the way. My rifle / results may differ from yours. Use caution and go up slowly. Mostly flattened primers, one session with a sticky bolt lift with Norma brass.
Best of luck with it !
