Used my LBT mould from the group buy for the first time yesterday. In the beginning I thought “not much different from any other mould” as I had issues with creases and such.
After the mould got hot I saw the difference. The channelled sprue plate makes it easy to hold the heat in and cast good bullets. I rarely had a reject once it got hot. The sprue plate is sharp enough where a push with the hand cuts the sprue. Also, lead spills and “dots” do not stick to this mould. They easily are removed.
