Trying to compare them online and cant tell much. How much finer is the EBR 3 vs the EBR 2B? Than the EBR 2? Already have a EBR 2B and wanted another but they seem like they might be tough to get. Was considering a EBR 3 because the finer subtensions at the top for figuring UKD. I have used a EBR 2 before and found it a bit fine on lower magnification. FWIW the EBR 3 will be on a TRG 22 260 where my EBR 2B in on my TRG 22 308 20"
