Walt Berger
When I was first getting started in bulletmaking I was having some difficulties both with my technique and a batch of jackets I had purchased from J4. Walt called me back a day later and spent an hour on the phone with me working out the problems and giving me lots of critical information, which I typed up and have posted on my workroom wall.
You're quite correct in your assessment of Walt, he's a great person and a wonderful source of top notch information. Unlike a lot of other experts, Walt is willing to share what he has learned with those who will ask. Thanx, Walt!
