Maybe interesting for some of you -here are some Chrono results of some .223 Ammo out of the 16,75″ STI AR. First measurement I did outdoor in Philippsburg with a L&S Chrono, second one was indoor with a Chrony with LED lights. The noticeable differences between both measures may result of different comps (nordic tac / L&S vs. Arredondo and Chrony) or maybe my Chrony measures a little bit fast. Truth maybe anywhere in the middle…

|Remington UMC 55grs||2962||2860||2911||871,73||160,11||L&S|
|S&B 55grs Schütte||3035||3088||3083||3068,67||941,22||168,78||Chrony|
|Geco Target 55grs||3036||3039||3031||3035,33||926,29||166,94||Chrony|

Concerning precision, the Geco 55grs and 63grs and the S&B 55grs Box are my favorites at 50m. At 100m, the Geco 55grs looked best, S&B I need to test on 100m.
