Greetings,
That is a pretty wimpy load, about 3 grains under max by my estimate. I note that the drop works out by estimate so it is possibly not a chrono error but I wouldn't rule it out. I would recomend working up closer to max and re testing. Sometimes light loads are not as good as those closer to max even with AR2206H. It would be worth sitting down and making a list of what changed from 100 to 200 metres. I don't thik I have ever seen that much velocity difference in AR2206H loads other than with very light loads.
Regards Grandpamac.
PS I assume that 40.5 grains was the charge. If not what was it?
Regards GPM.
