Below are my most recent loads I have been able to test. I hope it is helpful to others. The standard disclaimers apply, these are my loads that worked safely in MY gun, proceed with caution and replicate load at your own risk.
All loads were shot in my Ruger Precision Rifle Enhanced (Gen2) chambered in 6.5 Creedmoor. All loads were measured using a Caldwell Chronograph G2. I know the numbers are not the best but as you will see below I am playing around several powders, powder loads, COL's etc. so I am just providing some numbers for others to go by and possibly start with themselves as well as maybe introduce others to new possible powders outside of H4350. I have particularly been impressed most recently with Hodgdon's SuperPerfomance especially on the Berger 130gr Hybrids. I have not cared much for H414 but tried it based on postings by others. I may play with it a little more as I was very conservative loading with it since it was my first time using it.
