I must say I am rather pleased with a .450Nitro. I can shoot 300grain pills @ 2100 ft/sec for larger game like stags, kudus, pigs etc and it still regulate well. Using 480grain solids it can kill the biggest. Its a caliber I can use when I get older recoilwise and the gun weighs 10,5 Ibs. Investmentwise I would advice a first timer to get a good nice .450Nitro. It will over the long time bring most joy.
