Hi, I'm thinking of getting my 1st 45 cal. pistol but the cost of ammo is going to be doubled (i.e. 0.45-.50/round) than my 9mm ammo, which costs about 0.22/round. I mainly buy the Value Pack Remington UMC 250 rounds from Walmart. The same package is availabe for 40 S&W but not for 45 ACP. Can you share some sources of reliable and inexpensive 45 ammo in bulk package? I'll buy them for practice at the range. For personal defense, I'll get higher quality defensive ammo. Thanks.
