Yeah, speed kills. I am a believer on that too.

I also have always since I began been of the opinion that if I can make my load more accurate, the accuracy beyond the absolute minimum necessary to kill decently is insurance room for me to make a mistake in. Likewise, that flat trajectory is insurance room for me to make a mistake in range estimation.

Add those things to a bullet that is moving fast and kills better than a slow moving RN, and I feel like I have done the best I can to make it all come out the way I want when I pull the trigger.
