I like this idea and certainly could use the whiskey. I've never pursued custom load development as I'm pretty satisfied with the results I've been able to achieve myself. That said, I have done, and do like reloading for friends if they ask because it's usually not to difficult to squeeze sub-MOA out of a decent production rifle that they are only used to shooting factory stuff out of at say, maybe 1.25 MOA. Usually these guys aren't shooting that far and stuff like SD and ES don't come into play, and when they see .5 to .75 MOA @ 200 they are ecstatic! Then we have whiskey !Depends if it's make the recipe or make the recipe and ammo deal.
I do this for a few friends I don't charge anything and usually I end up with a bottle of whiskey or extra reloading components to use.
a big downside is a rifle that won't shoot.
I would clock my time during load development and charge accordingly. Ammo I would also clock and compare to premium loaded ammo
