Re: Reloading suggestions for .338 Lapua
Wind was good this morning so I got out to shoot some more test loads. I can shoot 300 yards out my back door, so that's where it was.
Did different loads and different seating depths for each one. 87-89 of RL25 and .030" - .020" off the lands with the Hornady 285 bthp. Looks like seating depth may be my issue. In every case, the .020" off the lands was much better with 88 being the best at 1.5" at 300.
My next test will be .010" off the lands with 87, 87.5 and 88 and see where that takes me. If all is good, I may have my load, or I may try to fine tune it with .1 or .2 grains of powder in each direction.
Do I need to be concerned with extra pressure going from .020" to .010" off the lands?
