I had used MG 124gr for my first 3200 rounds. I am using Roze jacked bullets in 10mm 180gr JHP and their 230 gr JHP in .45 ACP. Roze 180 gr in .400 and 230 in .451 are easy to reload, very accurate and open up sufficiently. I am hoping that the Roze 147gr JHP perform as well. BTW, Their service is great!!.
Thanks,
Chris
