Slugs in a 12 gauge?
So, I have a Remington 870 12-gauge, I use it for duck and goose hunting. It has a modified choke. I was sorting my ammunition today, (they accidentally got mixed,) when I found some slugs. 2 and 3/4 in 1 oz to be exact. I have two of them. Here is my question, is it safe for me to use these slugs in my shotgun as it is?
if not, what do I need to safely shoot them?
