I have found the .380 is very hard to find and when you find it, it is more expensive than my .45 ammo. I pay 14.97 for my Blazer Brass target ammo at walmart, when I have seen the .380, it is at least that high or more.
I hope that you are picking up your brass for that price, well for any price actually. I would reload it.
I do pick up my brass but I have not got into reloading yet, I usually shoot a box of 50 through my 45 about every other trip to the range, I have a couple of 9mm's and a .40 I also shoot, ammo is a little cheaper.
