I would try 140 gr SMK's and if I could not get them performing I would drop to 123 or 130 gr SMK's.
Weight is just part of the equation. Length is as much or more of a factor. Hence, Berger with the long VLDs recommends 1:8. ...same would apply to SMK in my opinion.
Get the specifications of the desired bullets and run the numbers on JBM.
There's no sense screwing around with marginal stability. ...unless you just feel lucky.
