Almost a year ago I adopted this rifle. Recently I got a 10x Unertl, so a step closer to being able to attempt to shoot it. Any advice in the care and feeding is welcome. I’ve been a patched round ball shooter for years. Paper patched bullet shooting is foreign to me. It’s 1-15 twist, .357 outside bore diameter. With pristine bore. Nebraska is far from a hotbed of slug gun shooting so local knowledge is nonexistent. In search of appropriate bullet and data to shoot it.
