McGuire ballistics

Has anyone used any of these? I'm wondering if these bc's are realistic. Real interested in the 160 grain 7mm bullets. Also curious if alternating between the mag fed or single feed options has any real world poi change.

I have shot both the 160s and 143s out of my 7SAUM, both the mag feed and single feed as well. The ballistics that they are advertising as their estimates have held up, or I have beaten them when I work through my different drop tests and run the calculations through different ballistic calculators. I haven't experienced any POI differences in shooting the two options, but have moved to shooting all single feed as my saum is built on a long action and doesn't have any issues handling the single feeds in my mag. The stiffness of the tip is the only real difference between the two and the single feeds from my understanding are only listed as single feeds due to tip damage when there is not enough space in the mag. Hope this helps.
