I have done some ballistic tests with some 300 grain 44 mag bullets at subsonic velocities. I used the Nosler hollow point, the Sierra soft point and the Hornady XTP. The bullets were shot at about 975 fps mv at a box filled with wet magazines from about 50 yds. In the first testthe magazines were tightly packed,in the secondI removed several magazines from the box to give it a looser feel. I was careful to place each shot into an undisturbed area. The Nosler shed its jacket both times and had the least penetration both times. The Hornady and Sierra both performed well with theHornady penetrating thefurthest in the tight mags and the Sierra penetrating the furthest in the loose.What promptedthis testis ashot I made on a200 lb wild boar from about 75 yds with the Hornady XTP. While the hog expired after a short 30 yd run I was not real pleased with the performance of the bullet. The bullet had total penetration without seeming to expand at all. I was looking for a bullet that would expand but hold together enough to exit at these lower velocities. Here is a pic of the bullets tested with the retained weights shown. The Noslers were weighed with the remaining jacket material. As it is I think I will stick with the Hornady although I would like to test the others on actual hogs. I plan on doing the same test with the Speer, Hawk Precision and the Ranier plated bullets. Any Thoughts?
