[QUOTE="BigGriz, post: 2145611, member: 88442"] Stag, I don’t mean to hijack your post, wondering if you made any progress. I have the same rifle and it is my first to develop a load for. I loaded up the following for pressure test and shot through the chrono. OAL 3.300 Nosler brass BR-2 primer 160 accubond H4350 48.0 gr - 2536 fps 49.0 - 2465 49.5 - 2526 50.1 - 2509 50.5 no reading 51.0 - 2597 51.6 - 2666 52.0 2693 Hodgdon max H4831 55.0 no reading 56.0 - 2527 57.0 - 2631 57.5 - 2597 58.0 - 2600 58.5 - 2735 59.0 - 2707 Nosler max I have seen no pressure signs yet. I would like to get velocity at least to 2800 fps. I think my next step is going to be to increase the 4831 load after deciding what increments. I am considering stepping down to the 150 accubond as I have some available locally. The factory 160 accubonds averaged 2810 fps but had an es of 98. [/QUOTE]
