Bingo, Well stated Grit..... I also agree on the RSAUM if you intend to mag feed. I'm in the build process with a SA Mag BF (6.5WSM), but i'm running single shot so OAL is not as critical. I was just playing with Manners Mini-Chassis two days ago at my 'smiths shop.... interesting idea, but IIRC OAL is limited to AI length? so 2.800 ish.... not enough IMHO. The Seekins WSM DBM will go to 3.100, which is darn near perfect for mag feeding & long bullets.
Keep in mind, the rumor mill is saying Lapua may start manufacturing 7RSAUM brass.....
That in itself could push one towards the RSAUMs (in any cal)
I just received my Manners MCS T-5, non inletted one color... 16 freaking weeks.... not impressed with the overall quality for that much wait.
Good luck on your build... & keep us posted.
