When I was stationed in TX that was my back up while hunting -though I never got the chance to see if it would work on hogs. I had a decent load worked up using 250gr RN cast bullet that was very accurate, don't know what the FPS was I didn't have a chrony then. But I wouldn't have doupted its ablity to penertrate a hog. Now you said your friend has a 45 LC- he should use it definately a better choice, get some Buffalo Bore rounds and it will go end to end on the biggest hogs!! If he insists on using the Old Army have that Casull close by. Just in case.
