Re: .308 190 SMK Reloading Data
Ive only found one gun that shoots 190SMKs better with varget than 4064 which is kinda strange when you consider how close they are as far as burn rate is concerned. That being said, varget is about a grain faster than 4064 in this load, so back off those numbers I mentioned earlier. Probably the most common, and popular load today in palma (where the use of the 155grSMK is not mandatory) is the 190SMK over however much 4064 it takes to get to 2500-2525fps. You can go a bit faster, but it really isn't any improvement ballistically.
