Yes, shot plenty of Boar (tough game) with the Amax, skin thickness of 1 to 1.5" and of the consistancy of a car tyre. Its something you have to get your head around though, you make a sacrifice in bullet integrety so that at long range where velocity is low, wounding will be broad. At close range, the explosive bullets can be a problem on tough game so you have two options, either use a different load or drill it into yourself that you have a soft load, watch your shot placement and be on guard for possible problems and if need be, rapid follow up shots.
Boar hunting can be a funny thing though, I have had bullets of every brand fail to penetrate skulls, core bonded bullets ricochet and soft bullets explode- but soft high SD bullets get the job done in a consistent manner.
Honestly, I will tell you what I tell my clients when it comes to the discussion of frangible bullets at magnum velocities for allround use (0-1200 yards)- use the projectile on all of your game (within reason, not talking Grizzly or cape buff here!), learn its strengths, learn its weaknesses and work to the projectiles strengths.
Hope that helps, Nathan.
