i recently bought a used Remington XP-100 with a Hart barrel and the usual accuracy enhancements. The previous owner suggested Fiocchi ammo (223 HVA50)with the 50 gr V- Max bullets as they shot well in this rig. Sure enough the gun shoots nice little 1/4” 5 shot groups with regularity. I then shot this same ammo in my Les Baer Thunder Ranch 223 and they are tack drivers in that Rifle as well. I have had little to no experience with Fiocchi ammo but it seems that this ammo deserves a second look if you are in the market for good 50 grain 223 loads.
