    As case capacity decreases pressure increases. Pressure = velocity. Putting them deeper, all things equal will raise pressure

    Pressure goes up, 0.25 shorter drops 2.5 grains for the same pressure

    ...... might have to pull a few then increase in pressure will increase velocity too ?

    I have loaded a new ladder at saami COAL from 60gn-62.5gn going up in .5gn increments, I will pull the 62.5 and 62gn loads I am skeptical I will even get that high in the ladder as will be on high alert for pressure signs after todays session.

    Is that accounting for the 19" barrrel ?
    Sorry for all the questions and thanks for all the advice I do appreciate it
    Will definitely pull anything higher than 61.5gn

    Yep, only way more is zero scales with primed case on and weigh the water volume
    they are only predictions, as always work up
    better than eating the case pressure, seen that once, don't need to see that again anytime soon
