I am thinking about trying some trail boss in a 338 Lapua to test low end expansion with the 280 grain Barnes Lrx. Barnes says they will expand down to 1600 fps in water so i figure i will need about 1700 fps to get 1600 fps at 100 yards. Do you think i can get this velocity or even anything above 1600 fps with this powder in a 26 inch barrel? Has anyone tried trail boss in a 338 Lapua? Or will i be one of the first?
