Just got a T1X and was able to put some rounds down the barrel yesterday. I fired several different types of ammo, that of what I had on hand and mostly to see the function of the rifle and get familiar with the scope which is the Arken EP5. It shot the CCI-SV very well and the Lapua CenterX really really good. It shot the Norma pretty good also. The Aguila super Xtra I believe it wants to shoot well.
