Based on all the info I have seen recently I’m starting to question why anyone would choose a 7mm over a 6mm. When considering bullet drop and wind drift the 6mm is almost always better. Am I missing something...? Should I trade my 7 in for a 6?

I guess I was comparing it to a slower 7mm (I was looking at 7/08 numbers). I think the velocities I was looking at for the 7/08 were pretty low and could be exceeded. Even looking at your numbers though im surprised the wind drift is so close between the two. Interesting to think about...
I just finished a 300 whisper and have been shooting it a lot lately, so I don’t mind correcting for bullet drop.
Flatlander , you're absolutely right , there is no comparison between the 6mm and 7mm . How the heck are you getting 2900 with 175MKs without stepping on your brass ? My last 284 had custom chamber with .004 increase in body taper , and I still couldn't get near the velocity you're getting . Of course I never shot Reloader 17 ? The 284 is an awesome cartridge !!

This 300 AAC Blackout or whatever seems to be all the rage now for some reason and people are acting like it's a new idea, I don't get it. I've always saw it somewhat as a copy of the Whisper that doesn't quite match the performance of the Whisper.
300 AAC BLACKOUT exceeds the performance of the Whisper. It has both a higher chamber pressure and a longer throat - so it is like 5.56mm compared to 223.
But what is special is that it was approved by SAAMI and has low cost ammo coming out.
