Here are the test results... the 16 gr averaged 1500 FPS while the 17 gr averaged 1600 FPS and was more accurate at the 25. I was shooting them through that M48 that I was having the issues getting the lead out of last summer. I checked and found no lead after shooting the 16 gr but I still have to check the 17gr.

These definitely chambered much better then the Lee .324 round nose mold I was using and I was going to ask about the COAL. This MP mold didn’t have a defined crimping groove so am I free to set the depth between the last lube groove and the rounding of the bullet as long as I’m able to chamber the round and not hit the lands.

@mac1911 pointed out I can increase my COAL a bit. All and all this was a success in my book and those 17 gr shot better at the 25 than the original FMJ factory loads the brass came from. I’m going to stick with the 2400 cause I scored four pounds the other week and now I have to free up some brass so I can experiment some more. I don’t have a ton of 8mm brass. More to follow as I test more but I really appreciate the advise.
