I would try them anyhow at a 1-10twist the Berger twist calculator is saying marginal results with a loss of 4% of the bc. Only one way to know for sure is to shoot them. I seen chachinga is making a 140 gr .257 bullet, that would be interesting but I bet it won’t be very accurate with out a special twist rate. Swift also makes the scirocco 2 in 100gr.
