[QUOTE="Mikecr, post: 3040149, member: 1521"] My seating test mirrors that described by MagnumManiac. It is group shooting, 3sht for this normally tells me enough (for just this much). The thing about seating is it's VERY coarse to results. Huge. So at a mid charge I can be throwing out 1/2 to 1.5" 3sht groups with seating changes, and that's ok. It's easy with that to spot optimum coarse seating. For me it has been rare that my barrel tune, providing ladder flat spots, has been within reach of an optimum powder tune. OCW started out as a search for a forgiving load, based on ES/SD. That's not what I have been doing, except when I shot a Browning Boss barrel. With a barrel tuner I could just shoot an MV ladder (in a sense), and from a flat velocity, adjust the tuner to put barrel tune on top of it. Without that, I initially focus on barrel tune (ladder), and only mind load density and pressure with powder. I could picture a balance needed at great distances, and I would want a barrel tuner for that. In my view, that's >600yds. The last barrel I developed with ended up barrel tuned with an ES of 8fps -without a tuner. That is just luck. The abstracts in this will never be predictable with math, so statistics are useless for ballistics. To reduce noise you have to take everything to baseline standards. Remove variables. [/QUOTE]
