Accuracy loads in manuals arepretty muchmeaningless anyways andCOL is not much better.The so called accuracy load is simply the load that was the most accurate in the test rifle and it should not be expected to be the most accurate in any other rifle.In some cases,it has been one of the least accurate loads in rifles that I have loaded for.As far as COL is concerned,there are great variations in throat lengths so you really need to determine the COL for your particular rifle.
