Excellent ammo - Hornady Black .223 Remington 62 grain Full Metal Jacket (FMJ) Brass Centerfire Rifle Ammunition

Hornady Black ammunition is an excellent choice. I've used the 75gr Hornady Black 5.56 SBR ammunition too. I actually would have purchased more of the 75gr 5.56 SBR ammunition but it was out of stock. I have a 5.56 rifle with a 10 inch barrel, and 1:7 twist. I believe that for home defense distances, this ammunition is adequate. I prefer the heavier projectile out of a shorter barreled rifle. Hornady Black isn't cheap ammunition but I shoot about 200 rounds a month or every other month. At my usage rate I buy this ammunition because it is very good quality in my opinion. It does seem to have less flash than other Hornady ammunition. I use a four piece Bulgarian muzzle device that kills the flash quite well, but with Hornady Black, it is virtually nonexistent. If you are looking for a well made, very reliable ammunition, then I think you should purchase a couple of boxes to try for yourself. If you find you like this line of ammunition, then you could feel better about the investment you make when stocking up. The 5.56 SBR ammunition might be hard to find because it gets bought up quickly. The .223 62gr will be fine in my opinion, though not optimized for your SBR.
