So I know this has been covered, I remember reading threads on it in the past but I dont have time to look through ALL the threads on here and I can't search because all of the key words are too short....Anyways... Which of these cartridges is better for the larger 30 cal bullets such as the 210 and 200's and why? I have a 300 WM but my magazine is so small that these bullets are seated way deep in the case. I want to have a repeater so just saying load as a single shot won't cut it. So I thought about maybe building a 300 WSM on a long action to have plenty of magazine length for whatever seating depth I want.
