Big Jake,
I've got no suggestions for loads, but I'll be watching this thread carefully. I bought the same rifle you have about a month ago. Everything seems short about it- including the mag. It did manage to shoot a couple of very nice tidy little groups with Hornady 250 grain Spire Points being pushed by a starting load of 44.5 grains of H4895. But overall, I've only shot that rifle once so far, so I've much to learn myself.
So far I'm totally loving the .358 chambering, but the Micro A-Bolt II is taking a more proufound "Getting acquainted" period than I'd have expected. It has it's idiosyncratic ways, but overall, I got nuthin' to gripe about. It feels great, shoots nice, tight little groups, looks attractive, etc. It just has very different characteristics than the Savage that was sacrificed to get it.
