Strange Day Good Day

[laowho]

Exactly Bruce. First off, as Kurt recommended in another thread, I went with batches of 5 rather than one. I'm droppin to 3 so that I can accommodate 1/2 gr increments. Secondly, I wasn't sure what the compression was doing here. Thirdly, I just couldn't figure on goin to later seating adjustments just to begin all over again, and yeah, I've read the papers available from Audette.

So my plan is this, based upon what I know so far--that my Saeco 645 @ 485 gr really likes the Swiss 1.5F @ 68 gr with a backset of 1/16th" I'm beginning in earnest now with the spotting scope @ 200 yds and with the bullet engaging the rifling (no more jump), and with the added pressures (less so for our caliber, but still) figured I'd start some "laddering" w/ 3 shot groups @ 66/66.5/67/67.5 and 68. I'm also feeling and listening for that sweet spot we get sometimes. Hope this makes sense. Figured Audette and Newberry were just givin us (the rifle's) window for charge measure variations that can happen when throwing (the vert plateau), and that barrel harmonics (nodes, even the shockwave muzzle expansion/contraction of Young) are already in that mix w/o the need for further teasing out.
