In this paper we present best-known merit factors of longer binary sequences with odd length. Finding low autocorrelation binary sequences with optimal merit factors is difficult optimization problem. High performance computations with execution of a stochastic algorithm in parallel, enable us searching skew-symmetric binary sequences with high merit factors. After experimental work, as results we present sequences with odd length between 301 and 401 that are skew-symmetric and have merit factor F greater than 7. Moreover, now all sequences with odd length between 301 and 401 with F > 7 have been found.
