I have purchased Federal 'Tactical' HST 9mm +P 147gr ammunition (P9HST4) to use in my 9mm carbine. I have a new red-dot electronic sight for the carbine that I need to zero. While I would love to blast through my actual stock of HST ammo to zero the sight, availability and cost prevent that from easily happening. Also, unfortunately, I cannot find any FMJ training type ammo to substitute. The obvious choice would be to look at Federal's American Eagle line. I did not see anything comparable. I emailed Federal and they confirmed the fact that they do not manufacture a training round with similar ballistics as the P9HST4.

I have looked at all of the brands that I could think of (Winchester white box, Remington UMC, CCI Blazer, Speer Lawman, Magtech, etc.) I did find one round on Midway USA's site that matched perfectly. According to Midway, the Fiocchi 9APD loading matched the HST ballistics exactly. However the product was out of stock. So I searched other sites for the same Fiocchi round. I discovered something odd. Some sites listed the same ballistic info as Midway USA. Some sites listed ballistics that were totally different. So, I decided to look at the Fiocchi website. Even odder... the Fiocchi website listed a third set of ballistics that were different from the other 2 sets.

To wrap this up... can anyone help me find a cheaper and more readily available round to zero my sight and train with?
