correct me if I am wrong. If insurance have to pay for lost or destroyed luggage, insurance will pay a miserey per pound of luggage. Montreal and Warsaw conventions fixed the value at 2.15 euro per kg (1.50 $ per pound) what have your rifle reimbursed 18 $at best.....lest alone binoc, scope, range finder, cams......
As luggage weight is limited to 60 lbs, you can obtain 90 $ for all your lost kit
