Your best source of reloading data is your manual...
Not quite true. It is great for a reference but not for what is the best load. Nice to hear from folks what 'they' use as it makes for a good starting point rather than fumble around 'looking' for a 'good' load :) . Why we have loads like the Skeeter load and the Keith Load and so on. Experiences from others can help jump start our quest for the 'perfect' load :D . Manuals are good to make sure you aren't given a bum steer.... Like if I said, load up 200g of Red dot under your 158g bullet.... And for working up loads of course.... But not the 'best' source of good loads .... just raw data....
