As has been said, this site is all about shooting, and all procedures are ultimately resolved by groups on targets. Having said that, we are of course free to split all the process hairs we like, but at some point it starts to be less interesting to others unless they can see proof that it is useful for the particular type of shooting that they prefer. For instance, no one needs single kernel accuracy for short range benchrest, or really for anything that is less demanding than long range benchrest, 1,000 yard in particular. If one likes to play with the toys, as I often do, that is just fine, but we also need to keep an eye on whether splitting a particular hair matters at an actual target. I have tuned scales and with a web cam and monitor observed single granule response, but for the kind of shooting that I have done, it has not practical utility, other than knowing that my equipment is capable of doing that, which means that it is well up to lesser tasks. One of the down sides of these sorts of discussions is that less experienced shooters may come to obsess over a detail that in the total scheme of things may be totally unimportant, given the limitations in their desire and/or ability to address the other variables. Ultimately, in the pursuit of accuracy some things are more important than others. A lot of it has to do with things that have nothing to do with reloading, much less super charge weight precision. In the short range group benchrest game, if you have good equipment, all that is required is to stay within +- .1 gr. To further make my point, if you look in the NBRSA group records, all of the several owned by my friend Gary Ocock were shot with charges thrown directly from his powder measure into his cases, and as difficult as it is to throw 133, all of his records in the last five years have been shot with that powder.
