Quickload is a guesstimate. Albeit a very educated one, it's still just a guesstimate.
For standard powders in standard bottleneck cartridges, it is as good as any other load data - that is to say, the error is likely to be less than the difference in brass, primers, chamber size, etc that make up normal differences in velocity. Several component manufacturers provide their load data straight out of QL.
.308 and RL-17 are so common that if there was some problem, literally 100s of shooters would have found it by now.
Quite frankly I have no interest in further arguing the point. I'm correct. Coyote is ignorant. If he wants to go on believing otherwise, he can do so but it doesn't change the facts.
