I have not tried crimping yet, but I will on the next batch I load as I am curious if it will make a difference. If I remember correctly I am seating to an overall length of 2.550, I have not played with the seating depth as of yet either. So, there are two more variables I plan to work with eventually.
Since its shooting so good at 100 yards right now, Im just dying to see if I can play around with seating depth, crimp, different powder to see if I can get it to shoot under an inch at 100 yards. I do believe the barrel is capable of it...I just need to find the magic combination of componenets that will do it. Gonna be fun getting there for sure.
