I recently used the 143 hammers in my 7mm RM. I found that even my 1:9.25 twist did not stabilize them enough to get maximum BC. Crazy accurate, and crazy fast, and once I figured out how much the BC was compromised by the lack of twist, they all impacted predictably and accurately out to 800 yds. I'm a happy guy. You just have to get the right hammer.
