I like what Eldequello had to say about this one...looking at the Nosler # 4 manual at home the most accurate load is going in the mid 2900 fps.. that is some formidable load and I have never used it before stoppping at 160 grain partitions for everything including Elk. My brother who I am almost ashamed to say is a one box of cartridges a year hunter uses 160 grain partitions in a Federal factory load that I gave him when he bought his BAR a couple of years back...he kills bucks regularly in our yearly Alabama hunt and they never move off after getting wacked by them...I mean down they go and his distances are the same as what you are mentioning mharris ...
