Is anyone aware of CASE shot having .95" iron shot loads? The field I am working was well within range for rifled munitions (and easily 20lbers.) However, there is no documentary evidence of Union artillery with 400 yrd range of this rear area and rather obscure field. In short, it is highly unlikely this field was within canister range, yet I have thusfar found a half dozen .95' iron balls (one showing impact.) Thoughts?
