I have a custom 40X, 3-Mod37 Remingtons left,a 1922 M2, and other RF rifles. I have 2 bricks of Eley Tenex in 2 different lots, 2 bricks of Fiocchi Super Match, several bricks of various Russian ammo, RWS, 3 bricks of CCI Minimag, 2 bricks of Western Super X,1 brick of Federal Hi-Power and 2 bricks left of Aguila SE. I have a few boxes of various other RF ammo.
The Aguila SE is the most consistent RF ammo that I have shot in my rifles. My SE is an old lot and is marked Eley primed. Maybe the new stuff isn't as good, but I doubt that.
