I find QL invaluable but it's only a computer model. The German engineers lean on the conservative side, probably to avoid the hassle of potential litigation. It's not a bad program to use with AR loading given the AR receiver is so unforgiving to over-pressure. I use it in conjunction with bullet and powder manufacturer load pages. Any load advice from other people including this forum is also considered but there's not one source that I treat as definitive. QL lists SAAMI or CIP limits which seem to be slightly less than the recommended loads on this forum. I am happy using QL limits knowing that means I have a little safety fudge factor on top. The target and the animal is not going to notice a difference of 100fps. Sure, some pressure/velocities are more accurate than others so it's all about setting a limit and finding what's the most accurate load closest to that.
