[QUOTE="Mike Matteson, post: 2221322, member: 101791"] I don't think that .1gr is fast enough especially where the case is holding about 70gr of powder per load. I generally move up .5 gr looking for pressure signs at the same time. I will load up about 15 case with the .5 increases, and go to the range to shoot. I chart where the bullet hits, and how the primers are looking. Once I have reached a flat primer I know what the max powder load is. You can ladder test a same time. If going up .1gr increase load it could be about 50 rounds to find max load. Looking at the ladder at the same. So if you are putting out 5 shot groups, that could turn into 250 shots just starting starting out. Yes you can just shoot one shot @ each .1gr increase, but that a lot of shooting to fine out too. On 300 WM .5gr increase isn't out of line. Where the rifle is using 70+ grains of powder to start with. Other rifles in the 50 to 62 gr loads I move up at about .25gr increase per case. [/QUOTE]
