Question on seating bullet deep or shallow in case?
Aside from pressure differences, does this have an effect on accuracy?
Not jumping bullets, seating into lands or neck tension, just the depth of the bullet in the case or neck.
Thanks
Like neck tension, there's a change in the resistance for the projectile to move due to an increase or decrease in the surface contact between the projectile and the neck. Does that have an effect on accuracy? Yes, but it's so small that it's probably not measurable on paper even at distance. Defiantly, it's not anywhere close to being a major factor in which it changes the interior volume, thereby significantly effecting pressure.
PS: Only other accuracy issue I can think of is having the projectile seated enough to maintain some concentricity . . . especially when feeding from a magazine. If concentricity is too far off, accuracy will suffer.
.I'm sure it does but I don't know what or how.
I do know that many models make simplifying assumptions that are just that simplifying. For instance the standard friction models are proven inadequate at every drag race. Seems that for a car to accelerate or brake at better than one G implies a cog railroad sort of tire friction contact patch.
As long as the load is developed in given seating condition, and that seated position had proven as best, good load density, and dismissing all else, I don't see how the condition itself would be a benefit or detriment.just the depth of the bullet in the case or neck.
I have not found it to be a consideration. Its the secondary effect on bullet jump that would pretty much negate the depth of seating causing a positive or negative resultQuestion on seating bullet deep or shallow in case?
