[QUOTE="tim_w, post: 1815913, member: 11132"] Lets make a few assumptions first. Lets assume a straight chamber and ammo load. Bullet is in perfect alignment with the bore. Lets assume a perfect load density of say 100%. Lets assume fuether that there is no velocity change with seat chanhe or that its adjusted for. Now with that setup what do people think is the reason changing bullet ogive to land relationship effects POI consistency? What is it that the change is effecting. As even in **** near perfect BR chambers and ammo that have as close to perfect bore alignment to bullet we still are adjusting bullet seating effect group size. If it was barrel bend modes low freq harmonics they would have to be erratic to do this and they tend to be quite consistent. Point being the bullet would exit at the same angle and thus group well. So what is it we are effecting by making this relational change? [/QUOTE]
