I bought 5 boxes of Barnes Original 600 grain bullets (100) and 100 pieces of new Norma brass to load in my Ruger # 1 tropical rifle. I loaded 65 grains of Varget powder, CCI BR-2 Primers, oal 3.535". I shoot left-handed and like the Ruger. If you have hunted in Africa, you will know that hunters like the .458 because of the straight case, which allows the seating of the bullet further out over increased powder charges. I find the recoil of the .458 loaded with the Barnes 600 bullet to be very manageable. I also reload with 500 grain soft noses and monolithic solids. I have taken 2 bears, 1 black that weighed 450 pounds and a brown bear that weighed 1200 pounds. The 600 Barnes was a one shot kill at 75 yards on the brown, very impressive. I recommend the Barnes 600 for large dangerous game.
