no doubt
Oh, hit right, I have no doubt a .30 cal /154 at 2000 fps or so will kill a hog. A 150 FMJ will do same. The question is, will the Tula/Herters soft point expand and stop the hog cleanly, or not expand, drill through and leave a small wound channel and a hog that you'll need to shoot again, or will cover more ground than you want before it expires.
Porche928, I shoot the .311 Speer 150 in the x54R caliber. It is an example of a pointed, spitzer bullet intended for .303 Brit and 7.7 Jap velocities (and x54R) . The fact you are getting good results in x39mm is proof it can be done, and a credit to well placed shots. But I still believe a thinner jacketed slug intended for lowere velocities will give even better results. One advantage I have in my x39mm rifles is that both are bored .308 and I can use the .30-30/150 class slugs, and the various .30/150 roundnoses, without being limted to .311 diameter. The Speer .311/150 was available for the Brit and Jap cartridgesw long before x39mm became common and popular. I note in my Speer manual that the .311/150 is not listed as a slug recommended for x39mm, only the lighter 125.
