[QUOTE="4xforfun, post: 941781, member: 9172"] I guess that depends. First off, during initial load development I ALWAYS take powder charges to the "red line" so I know exactly where it is and how things reaact getting there. Now my load for one of my 300 WBY comp tubes was 74 grains of RL-25 and 210 VLD's. I had loaded that tube from 71 up to 84 grains, so if I were to change primers on that load I really wouldn't be concerned about safety. I would just try and find that "node" again. A chronograph is a BIG help here. On the other hand, most of my other tubes are loaded at the top node I could get to, or..near the "red line". On those I would go down 10 % and try and find that upper node. Now, if you are changing primers, you are doing it for a BIG reason, so maybe the speed on your old best node is not actually the accuracy node..that is why I say...start over. You have already done most of the work......seating depth, neck tension, and a reasonable Idea on the best speed. I would simply do another ladder test....x number of powder charges...one shot per charge, and find the "clusters" where 3 or so powder charges are in a "group". That will narrow down the number of groups you need to shoot. Just work up loads in that narrow window where they clustered together. Good luck, Tod [/QUOTE]
