It has been a while since I posted here, but not because I have been idle.
Although I found that the 180 shoots pretty good out to 100 yards (1900 fps / 1.5 moa), groups at 200 yards have been closer to 6 moa.
I started working on 202s but had mixed results. With my current powder (WC 680 - same as 1680), the case is right at 100% load density. I found that my mixed brass was giving me vertical stringing even with weight sorting the brass.
I made up a bunch of converted brass from one batch of PMC headstamp, and results improved. I got good 100 yard groups with the 202s at 2030 fps with no pierced primers. When pushed to 2070 fps, they still shot good, but I got some flat / pierced primers.
I did some 200 yard shooting today with loads where I tried to split the difference on pressure. I still got some piercing, so I think I will call it around 2050 fps (no chrono today). I was happy with the sub 4" group with the 202s at 200 yards even with significant wind gusts.
I will try to increase the OAL just enough to eliminate the pierced primers. Another 0.010" - 0.020" should do it.
Another neat thing was bullet impact. Currently I am about 1.5" high at 50, 2" high at 100 and dead on at 200. I think I will dial down a couple of clicks to get 1.5" high at 100 and 1" low at 200.
