I'm that guy who just bought his first shotgun for home defense and accidentally bought the wrong ammo. I was reading about what shots are best for HD and ended up deciding to look for #1 buckshot. So I went into Academy sports and bought #1 steel shot not knowing there was a difference. It is a box of 25 for 20$ and they won't let me return it. My first thought was oh well I will just have some fun with it at the range and then I was reading about how steel shot can damage your barrel. What should I do? Will 25 rounds of #1 steel shot have that much of a significant effect on my new 12 gauge? As much as I love wasting 20$ I'm hoping to get some use out of it.
