I don't really have a budget for ammo Matt, not one I set myself at the start of the year anyway. Occasionally I have to decide not to shoot due to cost, but that's mainly around the travel costs than the ammo. Because I make my own ammunition it's a little cheaper...9mm at around 0.23c per round and rifle rounds at about $2.20 or so for example, but it's a difficult figure to determine as I reuse the spent cases, the brass, over and over so don't have to repurchase that each time. It's a lot though, the money I spend, a little scary to add up and look at the total figure to be honest.
Were you looking for a figure, a rough amount? If not ignore this, but it's about $2,700-$3,600/ year in ammo depending on how many competitions I shoot. Sometimes a little more, this year will be much less due to the virus.
