Range Report 300 blk vs all others

[KM375]

Can someone make a trajectory chart/graph of the 300 blk with its supersonic round 110 barnes out of a 16 inch barrel vs, a 6.8, 16 inch barrel using its best performing round, and 5.56 16 inch barrel with a 50 or 55 gr barnes, and 7.62x51 16 inch barrel using about a 150 gr barnes.
Or is there a free program that I can use to compare it myself. I have not seen a graph that represents all of these rounds together

What you need to find out is the "average" speed each of these bullets travels in FPS for your barrel specs. You can find the published BC for each bullet online at least "relatively close" from published manufacturer data. From there input the data into JBM and print your own charts and compare.

Your best bet is to ask if anyone has the rifle/caliber with 16" barrel and gather information from there.

I have seen the Remington pro-mo flyer, I just want to compare the 300 blk High velocity trajectory to the standard military rounds. Not 300 BLK but the BLK has similar trajectory to the AK.
