Yep. Was just out a couple of weeks ago. Using a Moss 930SPX with a primary arms ultimate weapon light. We ended up getting 6 pigs over a couple of nights. That was my first chance getting after pigs with a shot gun. What I experienced:
First night I was loaded with 00 buck shot, I hit several pigs with good body shots that did not go down. Ran off and gone. One pig took 3 rounds before he went down. Another that I had a good shot on was taken down by another guy in our group with an AR. Upon inspection he had several pellets in him but none were immediately lethal.
Second day, I was shooting slugs. Great improvement, significantly more damage and better chance of immediate (or close there in) take down.
If I hunt pigs with shotgun again, Ill be sticking to slugs. Otherwise back to the tried and true 450 Bushmaster.
