Looking for reccomendations on what different ammos to purchase to try out in a new 12FV 6.5 for best accuracy. We heard each gun can differ on what works best, but looking for a starting point. Did a lil, research, and heres a bit of list that came up for when we figuring on getting the 12LRP (which we didn't). Hoping to get some of you to comment of say what did/didn't work well for you. We usually use SG Ammo, but any reccomendations of any places or ammo would be appreciated.

140 ELD Hornady
Winchester 140 Match
140 Berger VLD Target
123 Scenars
Burris XTR2
120 Amax

Also, we got a .223 12FV, also, and kinda the same question for it also. We have some WOLF GOLD, but thought maybe what would be the next steps up from that w/o getting to expensive. We know the 6.5 ammo isnt going to be cheap, and want to get some pretty descent stuff, for it, but at the moment want to think semi economical for the .223, thanks
