They were first introduced in the mid to later 80's and the flyers touted the tip not bending and the long range accuracy. I was a kid in school and not a reloader yet but read everything I could find. A friend had problems with them on an elk in the mid 90's and when he called Nosler they told him it was an accuracy bullet not a big game bullet. The solid base was a very good bullet, we used them, and the BT did not really replace it. When the BT got real popular they cut the box size to 50, to help meet demand,
the price got a little higher, and then they dropped the solid base. They were still making them for someones factory loads a few years ago as I saw them sold as overrun.
