[QUOTE="rcoody, post: 1136689, member: 91090"] always remember change only one thing at a time yes seating depth can certainly change a group like that. Some bullets are more forgiving than others. Remember as you seat a bullet deeper you are removing case capacity. This can affect velocities and pressure. It also affects barrel harmonics along with the jump to the rifling and how that bullet hits the rifling. finding that sweet spot of powder charge and seating depth is better done in a very organized manner. It will make a huge difference when you find it. [/QUOTE]
