You don't need cheap dig calipers, the cheaper dial are better. There are no cheap/good dig scales. Cut corners on other stuff, but you need a reliable/accurate method for measuring powder. The Dillon beam is the best cheaper beam scale IMO. A $25 dig scale isn't even a good paper weight.
SUre it's going to cost you some $$, figure a decent ss press setup or Lee Classic Turret, right around $300. You'll pay for all of it in less than 8m if you only shoot 400rds of 9mm/m. Of course, anything less than a LCT is going to cost you a ton of time.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
