I have been using the 275 LBT in 44 mag for awhile and have never recovered a bullet on hogs. The load is 21 gr of H2400 with a regular CCI large pistol primer. I was surprised very much as to the penetration of this load on the Buffalo. It seems to be the perfect combination of velocity, penetration and dispatching ability. The velocity in a 7.5 in barres is around 1465 fps. On the buffalo the Guide told me to shoot the first one behind the shoulder. When I did this the bullet went all the way through and hit the dirt behind him. The second shot I put through the shoulders for fear the bull would run or worse at least it would slow him down. The result of this shot he went down in his tracks. I truly did not expect this from a 275 gr hard cast precision cast bullet. However, I did the same thing on the second bull with the same results. The finishing point was from my dad of 83 , now gone, dispatching another asian bull with his 44 mag old 3 screw with the same load and same bullet with the same shots. This one is special to me because he is gone and had and used that 44 mag since I can remember. He always used it and wore it every time he hunted. He only hunted with that gun and only used it to hunt and always with cast bullets. First with the old Keith bullet and on his last hunt I convinced him to use the 275 for the buffalo. He was an excellent shot and excellent mentor and the 44 mag was the only gun he would use. I would bet he is in the hereafter still toting his old reliable 44 mag if he can. Sorry for the emotional note but he is my dad. By the way my mom also always carried her 44 mag of the same type and they always hunted together with their old 44s. Have a good one.
