Be careful in playing with that rifle since it's equipped with the BOSS. Every single load is going to require a different "sweet spot" and you'll spend all day figuring out which works best for that particular load. If there is ever a rifle which requries a "rifle log", it's a BOSS equipped rifle.
A rifle log is a the record book for one particular rifle. You enter date, time, range, weather condition, wind, distance, target type, lighting, loads and because of your BOSS, your BOSS setting and scope settings. (For loads, you may want to start classifying them according to bullet type, powder weight, primer, etc.). After every shot, you make an entry into the log. The way I do it is to adapt a single sheet to account for up to 10 shots of the same type of load. There should also be a section to record your point of aim (POA) and point of impact (POI).
Everytime you make a change in your BOSS or your scope, make an entry into your rifle log book. This will give you the data to study and predict how your rifle will react given certain loads. It's very labor intensive but will yield invaluable data. It also helps you establish your base line to start from. With the data in the book, you can restore the rifle to its normal settings and adjust for a different load.
Does anybody know of a website where DCB can download a logsheet?
