Now the question I have is in regards to the Extreme Spread and Standard Deviation of the loads. The Loads for the sig produced an ES of 38 and a SD of 19.3, the load for the Tikka was a little better with an ES of 23 and SD of 11.8. What surprised me the most was the 6.5, it produced an ES of 88 and SD of 31.9.

I use Lapua Brass for the 6.5 and run 48.5g of IMR4831. I manually weigh each charge on a digital scale and check throughout the process with a balance beam scale. Bullets are 140g SSTs, which was not my number 1 choice but they shoot so well I decided to just keep running them. What could be causing these higher numbers? My process seems to be working based on the other loads but this is perplexing.

Any help is greatly appreciated.
