Good thread guys. Can't really add anything but it's a lot of good information to digest Being fairly new to reloading it has shown me some things I need to work on.
Something that keeps coming up in my mind is my methods for powder measure. At one point I found myself using four different scales to measure the same charge to see if all agreed on the amount. And yesterday I came across a thread about a lab quality scale that will measure the individual grain and that got me to thinking that maybe if I used it then I can shorten the distance between my lowest velocity and high velocity.
What are your thoughts on going to this extreme for powder measure?
I currently use the Hornady LNL auto charge powder dispenser and I also have and RCBS 1010. Are these tools enough or do I need to step out and get this particular scale?
What are your guys's thoughts on what is enough for proper powder measure?
This is a 243 test I ran. All 1X R-P brass. All trimmed. All weighed charges. The only variation was in the amount of crimp pressure applied to the case with a Consistent Crimp Tool. ((If you ask I have 3 studies on it)
SD's and ES are all over the place but best groups are interesting. The groups moved POI based on the amount of crimp pressure.
