45ACP is comparatively about the same cost to 9mm for me because I can use lead. Most likely there are combinations of arm and handload that would yield low leading but I prefer simple. Ammo must work for all chambered for that round.
although i disagree with the lack of savings in 9mm, the cost of shipping is not an issue. alot of "bullet centric" online stores do flat shipping. like graf's, mine and alot of peopes go-to, is a 8$ flat rate no matter the weight.
