    I have to admit that Mark that Satterlee I just haven't found reliable at all, except for one specific 223 load, when it was on the button.  Brass has to be batched by volume, annealed, FL sized, checked for length and loads dispensed to within 0.1 grain, and whilst the shooting technique is removed from variables, it's just not proved anything to me except that plateuas exist but where they exist isn;t necessarily on a barrel axial node.  Despite low ES on some, they haven;t groupe well, and if they won;t group at 100 yds then they won't group further out either.  I trust OCW more as I've had repeatability with that method and every time I've picked an OCW node, it's always worked well at distance.   You have a point on the seating distance though.  I usually load to book OAL recommended in the powder charts, shoot the ladder or OCW, pick the node and take the velocity flat spot, then have a play a little way either side with seating.  With VLDs, I try and get as close to the lands as I consider safe, depending on the chosen load.  If loading hot, then 5 thou is close enough to avoid a jammed round.  I do check all base to ogive measurements for all close to lands loads though to avoid any nasty surprises!

    All my previous loads  for different calibre have been worked up using OCW; but thought I would try the satterlee method for the first time with the 6.5 creedmoor and see what happens, perhaps I have dropped lucky just this once.

  2. Thanks for this, informative data for the RS powder and satterlee.

     I also recently used the 10 shot ladder for 120gn Nosler ballistic tips, but with Viht N135 powder - large rifle magnum primer,  And identified 2 flat spots, one at 2840fps and one larger one near the top of the load ladder at 2940fps. ( I stopped at 40gr with 2997fps due to pressure signs)

    Long and the short of it was using 39.6gr of N135 at COAL 2.775"  gave the lowest ES/SD and further tweaking with seating depth and brass prep really tightened everything up. Happy days.

  4. I'm currently reviewing an Elliot and Brown special edition, MREW, watch, and as waterproof 200m, with very bright luminous markers and simple face, and also a really neat feature is the prismatic glass, being able to read the time easily at an acute angle. 2 straps, rubber and webbing, with retaining pins that screw in, not spring loaded bendy pins. I dont think the movement is anything too special, but it appears to keep time very well.
