    “1. Define your requirements - what level of precision and velocity do you require? This requires sensible calibration of expectations - chasing smaller groups than most rifles can produce, and more speed than your chosen cartridge can generally produce, is perhaps not well-aligned to reality. Book max speed minus 15-50fps per inch for your actual barrel length is perhaps a good indicator of a realistic expectation for speed.
    2. Select the most appopriate powder and bullet based on reasonably wide research, using good quality components
    3. Load 10rd at a powder charge (within book data) that you predict will give the velocity target you'd like. It will be easier to be more precise in this estimate with more modern cartridges with lower variability in data. I suggest using more modern cartridges.“[/I]

    I may be missing something in the wording but what I read here is that, based on your conclusion, we throw out the convention of working loads up slowly as a safety measure to avoid excessive pressure in any particular rifle, a convention we hear ad nauseum, and just load up ten rounds and go for it. No mention of even loading just one and checking for excess pressure, which still seems wrong, before proceeding to load up another nine or is every rifle the same now and this is not an issue?
