i used to be skeptical or Ron's bullet tests. Now i'm an advocate. The carpet and plywood are a very good simulation of a boar hog covered with 1/2" of dried mud. That dried mud can cause a bullet to come apart right now.
i like all three of the 300 grain XTP bullets. The .430 300 grain XTP has killed a lot of hogs for me. If a really durable bullet is desired then go to the .452 300 grain XTP magnum bullet. Driven by 140 grains of 777 in my Encore, the bullet penetrates both shoulders of a 350 pound boar hog.
