me and my son shoot at least 1000 rounds a month.
just shot 50 rounds of sw500 with a lite load.
my cost for a 9mm round is about .08 (i cast my own bullets as well)
sw 500 cost was .60 for brass that i will reuse
powder about .08 primer .04 and lead .04.
compared to 2.50 per bullet and you would probably shoot less then 10.
i save a lot of money i shoot as much as i want and do not worry about ammo cost.
and i find it relaxing. my equipment cost about $4000.00 one super 1050 a mister bullet feeder and a star re-sizer.
i should say that i load the 500 sw on my lee press.
i also reload .380 .45acp 30-06 and 44 mag.
