I've been using copper solid slugs the past few seasons during shotgun season. I find they get the job done, however several deer I've shot have traveled over a 100 yards despite being hit right in the boiler room. I previously was using Lightfields and more times then none, the deer didn't make it far at all. I switched because for some reason my gun began throwing terrible patterns with them . I tried the Copper solids and they shoot a much tighter group.

What do you guys use and if some use copper solids, how are you finding they perform?
