Sierra 177 smk?

That seems to be pretty smoking for that grain weight...Chad heckler smoked everyone using factory Lapua 175 scenars in worlds, id be surprised if they were loaded any faster than 2650fps.
I agree. When I do my tests I going to start my velocity at around 2550 then stop at pressure signs/2760ish whichever comes first. Will likely start with H4895 powder and go from there.
 
Small Rifle Primer is your friend in this endeavor. You picked a badass powder!
Haha thanks, I heard h4895 is one of the best for 308 win. I have a box of new lapua palma SRP brass ready to go! Still waiting on a 24” criterion barrel from NSS that should arrive within the next few weeks hopefully. I also want to get some good ol’ IMR 4064 but it seems overpriced/hard to find at the moment.
