Let see... $1 a round, x 800 rds month, is a car payment or two.
This can be managed, but you have to shoot enough carry ammo to be confident with it.
Unless somebody else is buying, practicing with FMJ or reloads is far more cost effective.
reload.
for pistol ammo, i load for between $0.5 and $0.20/ per round.
the more expensive stuff is the speer GDHP rounds for my .38super.
i shoot alot more than 800 rounds a month tho.
