if you get flattened primers and/or sticky bolt or brass flowing into ejector hole/marks on rear of case you are WAY OVER do not progress any heavier load..pull any you have loaded.
I personally DONT use a cronicgraph....Ive loaded for my own rifles for years and have good feel for whats getting hot,in mine....each rifle is different.
any of the OLDER /EARLY manuals have good info on this.
