The most absolute and easiest and not to mention least expensive method is to just NOT use chronographs and trust the data in the loading manual. I'm sure chronographs can be of much value but I have handloaded for well over 50 years and hunted with those loads here and in Africa on many species up to and including Elephant. In all those years and rounds I have never had a handload fail to fire and I have never lost a game animal due to anything other than poor shot placement. I'm unsure as to how a chronograph would have made my pleasure any greater,my rifle more accurate or hunting success any better. As I stated I'm sure for those really concerned with data they are invaluable.
