Well were back from Texas, my so, we'll just refer to him as old deadeye. Used my 45-70 to shoot a 150 lb sow on thehind quarters. We were using the 400 gr speers and needless to say there won't be quite as much sausage coming out of thehams of that hog. He shot the hog at about 60 yards using a lever gun level load. At the impact the hog rolled then got back up and hobbled off about 30 yards before expiring. With that kind of shooting I'm glad we had lottsa expansion. The wound cavity was fist sized. I found pieces of the jacket in the wound. The 400 seems like a great soft critter gitter. BTW my daughter shot her hog in the head with a 30-30, no tracking needed. Most of all the kids really had fun.
