I have a Swedish Mauser that I'd like to develop a 'heavy' bullet load for. Specifically, I'd like to load the 155 grain Lapua 'Mega' round nose bullet. This is on the heavier weight side and I can't find any data for bullets over 140 grains in my Nosler manual or online. Does anyone have any load data for this bullet weight? I would like to use IMR 4350 or IMR 4831 powder. Thanks!
