The 180 gr PSPCL has been the most accurate cup/core bullet in three different .300 Roys and my KSS .300 Win. And not by a little. Maybe cuz it has more bearing surface. G1 is only about .37, but kills stuff fine loaded to 2950 fps. Took a cow elk at just over 400 with same ballistics in a .300 Win. Have 2-3k left. So yeah, I load them. It is a great deer bullet so long as you don't Texas ht or expect to punch both shoulders. Generally find them on offside hide on deer over 150# dressed.
I loaded a lot in the nineties and killed a pile of game with the 165s in a 30-06 and 300 win. I worked up a load for a friends M77 Tanger that shot the 180s into a very small ragged hole.
