I have hundreds of pounds of lead shot from my shooting days. Some I leave in 25 pound bags and I have A bunch of triple thick baggies with different ammounts.
What am I thinking?? I'm thinking I need about 400 pounds of lead when sheeting A foam core wing and A couple of ounces for smaller jobs.
When we went to steel shot for duck hunting it was A learning curve, we discovered that if your shells got damp over the season you would be shooting solid slugs the next season.
That bit of wisdom means nothing, I just thought I would bring it up!!
