Thread: 308 150sst 45gr 2208

Thinks to look out for as you work up ( Id leave it at that I found the 150sst to be very very frangible at 2750fps)
Stiff bolt lift, pay attention to any increase in force needed to lift and open the bolt and inspect brass case heads for extrusion into bolt reccesses and "swiping" bright shiny bits where the bolt has shaved off that extruded brass on opening.

With soft brass (federal comes to mind) this will happen early ( it even happens with their factory loads often? But with a harder brass like say Lapua if you get to this stage its over max....back off a grain at least from heavy extrusion and shavings and dont go any higher! !
