Put together a load for my late friend Don's 300 WSM over a decade ago. He asked for a high BC bullet. I had some 230 Bergers and gave them a try. The Browning A-bolt with a BOSS has a very short magazine length of 2.8". Worked up to 61 gr of RL17 which yielded 2735 fps. I watched Don shoot his last elk, a cow at 300 yds. She took a step then fell over like a falling tree.

At the time the 215 hybrid had not hit the market. The 215 might be the perfect LR bullet for a 300 WSM.

So much for the issue of a bullet sitting deeply into the case. Thinking 2735 fps is awesome for a 22" barrel. Here is a pic:
