yeah, it does have quite a bit of flaws in the documentation, i didn't really notice them because i had several assumptions in mind. that's on me, sorry
i'm not really familiar with the legal part, but the nitration mixture's measurements are by volume, and as for the nitroglycerin concerns, single-based smokeless powder is far less powerful and prone to decomposition, so that's why i included it in instead of making the synthesis process be a separate document. it might not have been the best choice, but oh well. you shouldn't do more than 500 grams from what i've found, and i've only ever done around 100g batches. you should always be stirring the nitroglycerin and keeping it in an ice bath, using a thermometer to observe the temperature if you can. if the temperature ever goes above 30°C, you should take the glass container with the nitration acid and the glycerin out of the ice bath and pour it directly into the ice bath to prevent an explosion
the measurement of 0.162g is what i've found to be best, it's around 2 to 2.5 grains but i opted to use grams in the documentation
microcrystalline cellulose can be used but it also needs more a precise process which is why i didn't include it. modern manufacturers use it though so i might make a new guide with that in mind
thanks for the constructive criticism
