I made a mistake I guess I got some 130 grain Speer hot core which have a slight flat point instead of getting the sierra . Unfortunately I can't find the COL for using that bullet in 308 if any one does please share. I have a lee book but with that bullet weight it would be seating the bullet before the canulure.. Does anyone know which bullet tougher Sierra Pro hunter or Speer hot core? The SST's 125 have flat base with 42.5 grains of H4895 I tested it on a crude medium of water jugs it went through two at 50yds and left a dimple at back of third and retained weight of 61.1 grains. I just loaded 10 up using 38.5 grains of H4895 and will see how accurate they are and do same test. I must say the first two jugs was vaporized but I would have preferred confirmed expansion and 3 gallon jugs of penetration. My searched for FOS would be 2600ish-2700 at the muzzle
