Hi guys, most of my experience except the 6.5x55 has been with cartridges that were originally intended to be used with cast bullets and have either long necks or are straight or tapered and generally do not reuire GC as they are conducive to lower velocities.
In a more modern bottle neck case that has a shorter neck say .25" instead of .4-.5", if a bullet design necissitates a seating depth of .45" am I right in thinking that seating the bullet below the neck junction is not ideal in either a PB or GC bullet as it makes damage to the exposed part of the bullet more likely!
What I am asking is idealy for cast bullets would you seat bullets to the base of the neck and no deeper?
So do you want to look for a bullet design that is seated further out, look for a case with a longer neck or just seat the bullet to the require depth and try and find a load with the least pressure that will get you to the velocity that you want and hope the side of the bullet and the gas check being exposed to lateral pressure and heat (gas cutting) as well as rearward pressure doesn't affect accuracy too much?
In short how much might a bullet seated below the neck be damaged?
