[QUOTE="kcebcj, post: 734666, member: 10391"] There are fellas here more qualified than me to help you but here is what I do. With any new bullet or powder I start like 3 grains below the book max then work up half grain at a time while shooting through a chronograph. With each shot I check the velocity and the spent case for any damage or primer movement. If I reach the book max velocity before getting the max grains I stop. If I get to the max load before the max book velocity I take a few and decide if I want to take it a little farther. That is a decision that experience really helps with and needs to be thought through looking at all the variables. Usually at this point I try another powder or change bullets. Doing what you did jumping 2-3 grains at a time is flat out spooky. The book shows your load max's out at 75.2 @2900fps but that does not mean you can go that high with that rife and you really need to know what the true velocities are.. There are a lot of variables that affect pressure and marks on the brass as your seeing could be one. Was the bolt sticky to lift after the shot? Only a inspection by a qualified person or your local smith will tell you if the rifle has any damage. [/QUOTE]
