I use 2206H with them but there is nothing wrong with 2208 either. I haven't used BM2 with them. With 2208 or 2206H you should get 2.9k easily enough with a 20" barrel. Work up carefully and you will be ok. If you have a chrono use that to track pressure. High speed compared to the manuals means high pressure regardless of what your primer or case looks like.
Out beyond ideas of wrongdoing, and right-doing, there is a field. I will meet you there.

Thanks
