the best of the 22 ammo choices are;
winny all types
feddy all types
cci all types
eley all types
aguila, all types made by eley
golden eagle, all types also made by eley.
wolf all types, also made in the same plant as lapua and sk.
american eagle red/black box. made by Feddy. surprisingly cheap and good.
feddy bulk pacs
winny bulk pacs, avoid cci bulk pacs.
remington, in the orange box, or yellow box, both made by Eley.
THERE IS NO OTHER GOOD REMINGTON AMMO, IT IS ALL DONKEY SHORTHAIR!!!
Since those top 5 brands have about 20 diff types of ammo each that they load, that is about 100 diff boxes to test out right there, alone.
If you use this whole list, you are going to find some ammo, your rifle can really shoot. NO DOUBT ABOUT IT.
Did I mention that remmy ammo is testicular juiceage, and should be avoided?
