I have tried the Acme red 148gr wadcutter bullets in 38 and 357. Behind a fairly stiff charge of 2400 in 357 brass the bullets give off a sickening stink like burning plastic. Also benched, in both 38 and 357 brass, the bullets to not group as good as well made square based cast wadcutters. The difference is quite noticeable. I'll never buy any more.
