    running RL19 on 150 gn partitions (for bush 0 -300 yd) - would have to look up exact load, but less than 60gns.
    And 64 - 65 gn 2217 with 162 AMAX - slightly compressed load, but careful, slow trickle with lots of tapping during filling helps.

    Yes fair bit of tapping with 2217...even stuck one of the kids electric toothbrushes against the case but didn't make much difference.

    Based on my experience with 300saum in various bullet weights and your QL results I would walk straight to n550 and try that.

    Have you tried a long drop tube? I have a home made drop tube about 500mm long and I can get around 1.5mm further settle (depending on powder) in a 284 sized case.

    Have you looked into a VLD type seating stem for your dies? Some of these have a different taper inside to avoid the ring left on the projectile.

    Mine's is pretty crude - a piece of straight copper pipe left over from my house build. A funnel cut as required and epoxied to the tube.

    The secret then is to tip the powder into the funnel and create a swirling effect like water going down a plug hole. Much more effective than just tipping it into the funnel.

    Obviously still need to put your normal funnel on the case unless you can do something smart with the bottom of the tube to fit nicely to the neck but then it will be limited to just one caliber.

    Had it for many years and have meant to make a flash harry one but no need.

    I seem to end up using the slowest powders for my cartridges so most of them are chocka and need the drop tube.
