[QUOTE="Mike Matteson, post: 2777657, member: 101791"] I do a powder increase, and depending on what are the normal charge in a case is, sets the rate of increase. Under 60grs I go up at about .25grs at a time., If the case hold about 70grs+ I move up .05grs at a time. I start out the the low powder charge in the manual. (I do look at several manual to see what different there is). I load a single case with that powder load and mark it. Increase by the amount stated above in a single case. I'll have 10 -15 cases loaded with the increase powder. Also get in ladder test at the same time. I'll go up and generally above the max load shown in the manual. Some of my loads are 5 to 6 grs over max load shown. In my heavier calibers I am looking a 3300fps. Smaller calibers I am looking at higher velocities. I Watch the primers to tell me where I am at. I also watch for ejector marks, and heavy lift. It's not to often that I even get to creatoring the primers. I know that others go to heavy lift, and or ejector marks. I don't! I generally use single based powders. Most single base powders aren't as effected as much by temperture. All Powder are all subject to temp. So if you are using a double base powder and hot loads. Better check in the different times of the year. If develop in the cold weather, need to reduce the load and start back up in the hotter weather. Or the other way from hot to cold weather. I am after max velocity and grouping of about 1/2 @ 100yds and see how they are doing at 300, 400 and 500yrs. I generally don't have a grouping problem with that. If the rifle doesn't group need to change the loads, and or more work needs to be done to the rifle. Bedding, Trigger, float the barrel and few others items. There can be other problems. [/QUOTE]
