Out of my JR Carbine I was able to group roughly 3 MOA @ 100m with this ammo. Which was fairly comparable to most brass cased 124gr ammo. Compared to steel cased Barnaul which was 6+ MOA @ 100m, Blazer Brass is *very* accurate haha!
Compared to Remington UMC and Winchester white box, the CCI was on par accuracy wise. I did chronograph this ammo but my speeds will be out to lunch due to the 19" barrel so that won't be any help to you.
