I don’t know if I would use the 158’s, but that is just MHO. I have been using them in my Herrett to fireform loads and they are “heck-on-wells” on critters. But, I have found they don’t penetrate well… Side shots, no problem. Longways, they will not penetrate out of a mature coon and they have almost completely come apart. The core is complete gone and the petals are all the way folded back. “I” wouldn’t use them at all on a deer or pig.
