Re: Berger 168 VLD's and 4064 ?
If it's for a .308, my IMR-4064 load uses the 175SMK 42.2gr of IMR4064, Fed GMM Large Rifle Primer, and Remington brass.
After reviewing Military load recipes, I note it was common practice for the USGI Arsenals to use the same load recipe regardless of bullet type/weight, So I'd suggest this same load as a starting load for the 168gr VLD.
I obtained it from <span style="font-style: italic">Precision Shooter</span> Magazine, where it was intended (in the 175gr version) as a guaranteed supersonic load for use at 1Kyd out of the standard M14/M1A. I have shared it here many times, and gotten a lot of positive feedback, from bolt gun users as well, even.
