I'll be honest, I've not head of reloaders
deliberately targeting very negligible NT. The way I understood things (and perhaps I've been living under a rock
); the tighter the NT, the more consistent your ignition will basically be (and potentially lower your SD). This is especially true for faster powders,where crimping can sometimes also help. Very tight necks does come at the cost of overworking your brass however - that's the catch - case life can be shortened. So you aim for the middle ground; as tight as you can afford to turnover your brass...
There's also the risk of set-back when you chamber your round if your NTs are very mild - I've had that happen, and it can really mess with your line of investigation...
Now if your jump-to-the lands is really small, your ignition
will aided by this natural resistance. And some cartridges/guns are just inherently accurate, so you can afford to "lose a little" with so-so NT (but with a small jump to the lands).
Dunno, I could be completely off here boys - I'm basing this stuff on hearsay and personal experience... correct me if I'm wrong almighty gurus.
Stix getting back to your question of "powder vs NT angle" - personally, at this stage I'd be focusing more on NT and less on powder choice. In my experience NT is a far bigger contributor to accuracy than powder choice. That and bullet choice. Many guns will shoot a variety of powders pretty much equally as well, so long as your NTs are tight and consistent, and the barrel favors a particular bullet.
