[QUOTE="sedancowboy, post: 1983673, member: 85874"] I wonder if when we change seating depth that we are actually changing the timing of the release of the bullet from the muzzle. We are seeking the bullet to be released under a certain point in the harmonic wave at the muzzle for consistent hits on target so we adjust seating depth in an attempt to control the release of the bullet from the muzzle. I have been reloading for 51 years and the farther along I go the more important neck tension and seating depth become for consistent results. I might add that a good muzzle crown is very important to good accuracy. However I don't think any of this matters if you don't have a consistent chamber and throat with the correct leade. Hybrid ogives seem to be more consistent and less seating depth sensitive than the other two. While I have stated the obvious above to try and add to the question that we may never know the answer to. Is it the rifle or the bullet? It is both different styles of bullets might need different leade angles and different free bore lengths. Weatherby learned early on that a long freebore would lengthen the pressure curve or lower the peak pressure curve to acceptable levels without decreasing acceptable accuracy. Sometime read the Huston warehouse testing which has been published here in the last few months. Their results were bullets always jammed for best accuracy. My experience is that most modern bullets capable of the level of accuracy we have come to expect do best with some freebore and a 1 1/2 degree of leade angle. [/QUOTE]
