Hi Lindsay, the weight is 6.61 lbs.
From the owners manual - Never shoot steel shot loads in a full choked barrel or an improved modified choked barrel. To do may cause the barrel to swell or rupture. In general, steel shot fired with a modified shake will produce the equivalent of a lead full choke pattern. This will be true of all steel shot sized up to andincluding no. 2. The established improved cylinder chokes will produce the equivalent of a (lead) modified pattern. All steel shot sized larger than no. 2, and including special sized such as F, T, etc., should be used only with improved cylinder chokes. These steel shot sizes, when used in an improved cylinder choke, will produce equivalent to (lead) full choke patterns. The established cylinder choke or bore will produce the equivalent of a modified (lead) pattern.
Stay safe & have a great day!
