I've found Atlanta Arms very accurate and consistent (both the 115GR FMJ Match AMU and 115GR JHP Match (XTP bullet)). Out of my X5E Classic, I shot 25 yard 5 shot groups. The smallest 5 shot 25 yard group was 0.89 inches and the average 25 yard group (out of 5 groups) was 1.31 inches.
Apologies. I just noticed you are in Slovenia so Atlanta Arms is not likely to be available.
