In the EU we usually shoot European brands.
I believe Lapua is the widely accepted golden standard of match ammo.
Most people shoot Fiocchi, S&B and Geco (although its Hungary made ammo is really dissapointing).
The 124 Gr S & B and Fiocchi are pretty nice ammo for both plinking and Competition. I have a lot of friends who use these brands. They’re very consistent and accurate in my shadow 2, TSO and X5 when I tried them.
I chronoed them around 1100-1120 FPS and shoots nicely in my 8” gen 2 MPX as well. Bonus is I like loading the brass. Very consistent on my 650 after I ran the them (especially the S & B due to tight primer pockets) through my swager.
