Recently started shooting the Sig 320x5.

Found mine like the Bayou 124 grain TC, 4.0 bullseye seated 1.080. I have heard (from Bayou) they have DC'd he 124 TC in favor of the 120 TC. Just loaded up a batch with 4.0 BE seated 1.065.

Will report back how they shoot.

The 320 also did very will with the Berry 124 RN plated with 4.0 BE. Gun will hold B27 - x ring all day at 50 yards.
