We do use the large bore rifles on 10 mph days due to wind drift
if we spot a rock chuck (Marmet) in the rock slides or other "Trash" that the farmers & ranchers want help with.
The reason I tried the Hornady 75 gr HPBT match bullet was the book wind drift was pretty much the same as the 155 gr SMK I was using in .30 cal. You do need a 1-9 twist barrel though. And yes, the real world wind drift is pretty much the same. On my good days under 1/2 MOA.
I use Remington 7 1/2 primers and either RE15 or AR Comp. AR Comp seems a bit cleaner. Either will match factory velocity out of my rifle if not the book.
When it comes to accurate rifle loads, there's Berger Bullets with Varget and then there's everything else. This group was fired with a .233 Savage model 12.
I'm still a big fan of traditional cup and core bullets, and Sierras have long been my favorites in a variety of rifles and loads. My old Ruger flatbolt . 308 will make little bitty groups with the 150 grain Pro Hunter, and my Belgium Browning BLR . 308 likes 180 grain Pro Hunter roundnose, my woods rifle and load. The . 22 cal 55 grain Game King is a favorite in my . 223s, but the V-Max in same weight is great also. The only "fancy" bullet I shoot is the good old Nosler Partition, which I like in both 150 and 165 grain . 308, and the 175 grain Partition in my Ruger 77/7mm Rem. Mag. is my elk rifle/bullet. For my purposes, the higher priced premium bullets aren't worth the extra $$. The Nosler partitions are more expensive, but I look for the on the secondary market and also buy the bless from Nosler's Shooter's Pro Shop when they have my favorites available. I've often said if I had to make do with just one of my presently owned rifles and one load, it would be that old flatbolt Ruger 77 with its Leupold 3.5-10x scope and the load would be a 165 grain Nosler Partition. Not much I couldn't do with that. So remind me why I have all those others?
