I know that published reloading data needs to be conservative to account for the vast quality and tolerance differences in rifles and components not to mention liability concerns but just how conservative are they? I’m in the middle of load development for my first custom rifle and I’m right at or just above (depending on source) the published max load for my caliber/bullet/powder and showing no signs of pressure. Being fairly new to reloading I’m very cautious about pushing the limits any further. However, I am looking for a bit more. I have found information in the various shooting forums including this one that suggest I can safely push the limit quite a bit. I’ve found numerous posts with powder charges in excess of 10% higher than the published max loads. I’ve even found some that are in excess of 15% higher. Can the published load data really be that conservative? Are manufactures really leaving that much on the table? Or are there guys out there that are just willing to really pushe the limits?
