RE: .30/06 ammunition favorites!?
In my 700 BDL, factory Remington 165 grain CoreLokts work pretty well. I handload 165 grain CoreLokt bullets with 49.8 grains IMR4064, Remington cases and Federaql 210 primers and get great results - - ~1MOA, good performance on hogs.
Factory Remington 180 grain CoreLokts seem to work best in my 742. Handloading didn't really give me any particular advantage, but this gun isn't a target rifle anyway.
Strangely enough, neither of my rifles much cared for Winchester ammo in any bullet weight, or any handload or factory load with 150 grain bullets. I've tried Hornady, Sierra, Speer and Remington bullets in 150 and 165 grain, flat base and boat tails, and of all these I've gotten the best accuracy in flat based 165 grain Remington CoreLokt bullets. These are theleast expensive bullet that I have tried, too - - go figure!
