Thread: ballistic calculator's can be wrong

never heard of a .308 that wont stabalize a 150grn projectile!!!!! before now....... most will happily digest 180s and will do ok with a 200 round nose too..... try a faster load.... middle of road book data wise and see what happens... speer flat based pills SHOULD be better still if bore is worn/tired as they in theory fill the grooves in bore (some fancy word like obliturate??/) better than other designs. of seen as though you are reloading and not wanting a hot load...try some of shootersnz great cast projectiles....
