[QUOTE="woods, post: 941795, member: 6042"] This is true I do a ladder test (one shot per powder charge) at 300 yds to find a safe max charge at a velocity I am happy with (hunting loads at hunting velocities) [IMG]http://img.photobucket.com/albums/v663/bwestfall/TARGETS/DSC00968.jpg[/IMG] [IMG]http://img.photobucket.com/albums/v663/bwestfall/TARGETS/DSC00980.jpg[/IMG] not necessarily looking for an accuracy node since to verify I believe you would need to do the same thing 3 times to verify, just safe max and velocity. Then I do a seating depth test starting at least .015" off the lands (hunting loads best not jammed) and proceed away from the lands in .015" increments. Looking for an acceptable group with low extreme spread and low standard deviation [IMG]http://img.photobucket.com/albums/v663/bwestfall/TARGETS/1211-1.jpg[/IMG] and there is my load at .060" off. Velocity will decrease (in this example) approx. 10 fps per every .015" deeper seating and that is equivalent to approx. .2 gr powder. So (again in this example) going from .015" off to .090" off the velocity decreased 53 fps which would be equivalent to 1.0 gr powder. What you are doing is timing the bullet exit from the muzzle and, with the low ES & SD, looking for a consistent performer at distance. I always set my bullet grip at .003" since IMO brass reaches a certain elastic limit at .002" and a smaller ID will not increase bullet grip and only leads to more seating pressure which can put a hex on concentricity. At .003" I insure that all necks have reached the elastic limit and will have a true bullet grip of .002" [/QUOTE]
