All I am fairly new to reloading and would like some clarification on powder charges. I am loading for a 300 Win Mag using 215gr Berger Match Hybrid Target bullets. I intend to start with H-1000 powder and Federal 215 Match Primers. I have Lapua brass. I contacted Berger about load data in the 300 Win Mag and the 215gr bullet (see attached chart). The data shows a staring load of 70.5 grains of H-1000 and a max load of 74.0 grains of H-1000. In searching and reading several posts on this site, many of you are using more grains of H-1000 than the listed max load of 74.0 grains in the 300 Win Mag using the 215gr Berger. I understand seating the bullet further out of the case allows more case capacity for powder. But, I have read that you still should not exceed the manufacture's load data for maximum charge. Obviously, safety is my biggest concern. But, I would like to maximize performance. Is it ok to gradually increase the load until pressure signs form if you are above the maximum load stated in the manufacture's load data? For those of you that are using 75,76,77 and 78 grains of H-1000 with this combination are you having any issues? Your comments are most appreciated.
