This might be the most popular match ammo today. Lapua makes more expensive loads, but collective wisdom says none of it shoots appreciably better than Center-X in most rifles. It was, by far, the most used ammo at the NRL22 National Match in May. Partly because the most popular rifle, the Vudoo V-22, is chambered for it. Like Eley, if your gun really likes Lapua, and you're serious about competition, send the barreled action to Lapua, get a lot recommendation, and never think about ammo again.
