Spent the afternoon Wednesday at my usual haunt, the Marysville Rifle Club (MRC). The weather was perfect. Mostly sunny and right around 50°. Not a single person there other than myself for the entire three hours. I collected a lot of data for my .224 Valkyrie loads.
I shot five different combinations (ladders) of bullet, powder, primer and COL recipes, each with 5 round groups at graduated amounts of respective powders used. All groups were shot at 200 Yards. It was a really good day.
I found an Excel program that is sufficient for the data tracking for the time being. I've discovered that the the data collection and logging is time consuming work.
My best group of the day is pictured at the bottom. There were some other decent groups too.
