I concur that a load that produces the best SD’s doesn’t automatically indicate it can develop the most effective groups, and vice versa. I think a single is a lot more connected with circumstance design, powder, and inner ballistics, and the other is relevant to barrel harmonics and locating that “accuracy node.” In extended-range capturing, I place more pounds on reduced SD’s and superior team dimensions (want beneath one/2 MOA), in excess of Tremendous-little group dimension and higher SD’s. (Honestly, With all the Prometheus finding low SD’s is rather quick with most powders.
I assumed it absolutely was an excellent post. They went to some wonderful length (like renting a freezer truck) to try to acquire it suitable. That makes it a lot more annoying which the write-up is missing the charts and photographs. It seems like somebody copy-and-pasted it in from A different source and the images weren’t bundled.

Unsure why yet, as it had been just announced, but Hodgdon will imr enduron powders no more present any of the IMR Enduron products line of powders.
With the LabRadar, it’s straightforward to only report pretty much each individual spherical you fireplace on the assortment. So I from time to time history fifty shot strings.
