Comparing a sabot bullet and a conical is like comparing a dog and a cat, the conical is the old way with massive hitting power and a rainbow and the sabot is the new way with flat trajectory and the foot pounds of energy developed by high velocity.
The FPB is the most accurate conical in all 3 of my guns and it penetrates and mushrooms well, the SST on the other hand is the most accurate of the sabot bullets except for the new Lehigh, I use it for years and never had a problem have taken deer bear and wild hogs with it, I shoot it at 2000+ feet per second. I believe that there are better bullets for terminal performance such as the Lehigh and the Nosler,partition and for elk I would use a 270 or larger Lehigh.
