Yes and will this week but im thinking if they are that close in weight that they will have similar case capacities as well. I already loaded the heavier cases from PV and can say the capacity compared the the lapua is a huge plus, in the lapua brass 45g of H4831sc was about mid neck full and H1000 the case was full at about 47g with the nosler brass 47g(1g over book max for effect)H4831sc is just at the bottom of the neck and a max charge of H1000 is about mid neck at 50g. I will check the heavier cases against the lighter cases with water this weekend after I shoot them and report back.
Im just hoping they hold up as well as the nosler i shoot in my 300.
