What i'm trying to get at is that if i spend the time to get as close as i can to the rifle lans with the bullet but the bullet is just pressed enough into the neck to seat the bullet won't this cut down on consistent pressure build and release of the bullet?..So what would be better,.. if i had the bullet pressed into the neck just enough to keep the bullet in the neck but are very close to the lans without touching or is it better to have the bullet pressed into the neck of the case so the bottom of the bullet is even with the bottom of the neck to get a more consistent and better pressure build for bullet release?..I've been going for the as closest length as i could get to the rifle lans to prevent less bullet jump but now I'm stumped on which is more important or would add up to more accuracy? What got this stirring around in my peanut thick head is smaller bullets don't have the length as a heavier grain bullet therefore to achieve greatest bullet length I don't feel that i'm pressing the bullet down enough with smaller grain bullets to get the proper pressure build to get a good consistent bullet release... UUUHHHHH now what do I do??????????..Thanks for your time and help
Some rifles will be less picky than others, but bottom line, not all rifles will like a particular load close to the lands. You will probably find a sweet spot if you do some experimenting. Might be jammed into the lands, might be over .100 off the lands or anywhere between.
That said, you might read this thread on bullet to bullet variance. You might think your bullets are .005 off the lands when they might be .005 plus or minus .005 or more. This is what I have learned.
What to do about COAL inconsistency?
