I have a thought or maybe a question for you more seasoned guys than I. I have a good load for my .223, it shoots fair at 300, but tightens up at 500. I decided to play with the load. I shot test shots at 300 and kept 5 shots in the 3/4 in range. Noticeably tighter than my previous load that I have been shooting. I went and loaded 20 rounds of this new load and went back to the range to shoot at 500 with high expectations. I was very disappointed. All 5 shot groups were in the 3 inch range at 500 with no or undetectable wind. My previous load would consistently group 2 inches or slightly less in the same conditions.
My question is, is it possible to have one load for 400, 500 & 600 yards? Is it also possible that you can shoot even better with a specific load for a specific range? In this case, could I possibly find my accuracy is better with a different load at each distance?
Keep in mind, I am a new shooter at these distances, but I have been pretty consistent in windless conditions.
Does anyone have any thoughts on this?
