Made it out this am to validate at distance, was excited to see some results from 4-800 yards. Long story short, I am back to the drawing board for loads. The first time out I shot groups at 100 and 200 and had decent accuracy, probably 5/8 MOA. Not the tightest groups I have shot, but not terrible either. This morning was cold, but almost no wind, which is nice. My 100 yard zero groups weren't great, and things just got worse from there.
I thought it was me, or some scope or rifle malfunction at first, but luckily I had about 20 rounds of my old load with me and shot those. I put 3 in the same hole at 100, and then center punched every plate out to about 750. I looked back through this thread and it looks like these bullets might be a little more "finicky" when handloading....who knows? I did notice a definitive improved BC with the BD bullets, but even then I was catching alot of edge of plate or a little high or low. I certainly haven't given up on them by any means, but will have to revisit when I have enough time to try some different powders, primers, seating depths, etc. Hopefully I can find a "sweet spot" with these so to speak down the road. I got pretty spoiled with load development with this gun at first, I had a hard time finding something that wouldn't shoot. I will report back when I try some different combos.
