so, my brother finally got his browning bar (semi-auto) out of layaway, and picked up a set of dies. he wants me to load him up some shells. which i have no problem with. of course, with a new (to him) gun, and never before loading for an '06, i am faced with trying to come up with loads that will eventually be accurate. i started thinking about this, and i wonder, how does an ammunition factory do this? they test for pressure and speed out of a universal receiver from what i understand. and the barrel vibrations in that set up is going to be nothing like a sporting rifle. obviously, they are not just throwing a safe charge in the case, and shipping them out the door. either there is some formula they use, or, someone gets to sit and fire rounds for days on end trying to find a load that works in several rifles that they have on hand. that seems like it would be a major undertaking. and it would have to be repeated every so often to make sure that the production lines are actually turning out ammo that will be at least semi accurate out of most guns. i would like to get close in as few rounds as possible. i doubt i would be able to get first load success. but it would be nice to only shoot 5 or 6 different loads to get in the ballpark.
p.s. i have imr4350, imr4831, benchmark, and reloder 7 powder. i also have hornady 180g btsp interlocks, and sierra 165 bt's. and of course, cases and primers.
