Tentman, couple of questions
So all 3 the loads (39.5, 40 and 40.5) produce significantly better groups with H100V than 2209 ?
Yup - hugely better, about the best it'd shot with 2209 was 40mm, with H100V the first group was 11mm
What speed does 41.5 of 2209 give you ? Compared to the estimated 2870 with H100V ?
2940's
Was seating depth for the H100V rounds the same as for the 2209 loads ?
Yes
Some general comments from my side:
- I look for speed consistency first, using a good (non optical) chrony, and ignore group size. Once I find a good SD value for 5-shot strings over the chrony, I play with seating depth to shrink group size.
- It would be strange to find a "node" that is as wide as a full grain for a medium sized case like the 6CM. When looking for nodes I tend to use increments of 0.3 or 0.4 (around 1% of volume).
