We tried dealing with Adam, but it did not work out and commercial bullet makers will not sell ballistic tips. Tipping an open meplat is tricky. Crimping the tip is not easy. I use a tiny drop of super glue and make sure tip is secure...loose tips cause flyers. My volume is small, so pulling tips is ok.There is a guy on the Saubier forum from down under that goes by the name 'Adam' who makes and sells tips.
