[QUOTE="Kennibear, post: 874138, member: 51650"] Try a Sierra 200gr SpBT Gameking in front of 75gr of IMR 7828 in a WW case and a Federal #215 mag primer. This is an absolute max load (62kpsi on my Pressure Trace II) and top load in the Sierra Manual so start at least 1gr down. Clocks a solid 2900fps over the Chrony with a SD around 13fps. I am going to try Superformance next. This in my son Anton's 26" Rem SD Stainless/synthetic. [/QUOTE]
