I agree with you, but as I stated, it appears that 'x' amount of neck length has little bearing on accuracy if neck tension is consistent. It has long been believed that the 300WinMag would have been far more accurate if it had had a longer neck when designed. I have used the 300-338 case with it's longer neck, not as accurate as my 300, either is my 300Weatherby.
I feel that the throat design has more bearing on accuracy than how long or short the neck is, I'm not the least bit concerned with barrel life, I've been doing this long range thing long enough to not really worry about throat erosion, I just keep altering charges to keep the velocity where I want it and don't bother chasing the lands, when accuracy falls off I put a new barrel on.
These are my thoughts, not based on any known theory, just what I have witnessed myself and what I think is occurring. If anyone would like to steer me straight, I'll bevall ears.
