So yesterday, the wife was off shopping and I decided to replenish my 300 grain .45/70 bullet stock. This is with a RCBS 45-300-FN with one cavity hollow pointed. One of the drawbacks to a bottom pour pot is that it's hard to get light under the pot where you can see the lead go into the mould and judge the size of the sprue. You're just casting in the dark so to speak. I expeimented with a bare light bulb earlier but that blinded me. Several days later, I ran across an old motion sensor floodlight in my "stuff" . I attached a short cord to allow plug in and a shield to direct the light. Yesterday was the first time i tried it. Man, what a difference. Next time I cast, I'll position the light a little differently but this was a great help and I can see what's going on under there. You can "hit the hole" with the melt, insure that you have a filled cavity and allow a good puddle on top. You can bet i'll be using this from now on. Easy to rig too./beagle
