[QUOTE="Sam Summey, post: 1692308, member: 109601"] You already have primer cratering, I suspect the temp is above 90 degrees. The book max load is calculated based on safe pressure at elevated temperature. Does it shoot under a minute, then STOP. If it doesn't shoot that well drop back a grain and move up in tenth grain increments until you reach max again. If it doesn't improve before max reduce 10% and start over again. The max load should not be exceeded unless you want to stretch the action and blow the headspace. [/QUOTE]
