[QUOTE="RDM416, post: 488313, member: 3745"] rem, That is a great place to "start" and to stick with. I have log books going back over 20 years with my shooting and loading info. Thing is, the longer I play this game the more detailed my log books get. I used to just write down load, weather conditions, and velocity of each round. Now in addition to that, I sketch out groups with each shot numbered (not always but often). I will often make notes of something that did not perform like it should have so I can remind myself and think about it later, etc..... Write down everything..... then refer back to that data, that is where you will learn the most, not when you are actually on the range. I used to ignore spin drift and coriolis in my calculations and "dope". However, from real world experience I was quite well aware that the further out I shot the more my groups drifted to the right. At 1000 yards I would be about 1/2 to 3/4 moa right. I knew this and compensated for it even when shooting critters at those distances, so even though I did not understand WHY it was happening, my log book assured me it WAS happening so I compensated for it. After reading Bryan Litz's book on ballistics it dawned on me that the advice I had been using of "spin drift and coriolis are too small to matter" was BAD advice, so now I calculate and compensate for both. There is no substitute for range time, but make sure you are LEARNING something with your range time, otherwise you are just burning powder....:) [/QUOTE]
