565 Grain Long Round Nose (.501) John Ross Design

Can anyone provide the loading data for the 565 Grain Long Round Nose (.501) John Ross Design Boolit by Matt's Bullets. I've been looking around online and can't find specific data. John Ross' web site doesn't list this exact bullet. Any thing you can provide would be appreciated. Many Thanks!

Luke Pagel posted this on Matt's Bullets site. I loaded some of these rounds with 30 grains of h-110 and was able to hit a 6x6 steel target at 155 yards. Now I know you hunt game at that distance with this gun but it makes a statement as to the accuracy of this bullet. Date Added: 04/03/2015*by Luke Pagel

Recently ran into searching for data for the same boolit, starting load ended up at 34.5 H110 with Winchester large rifle mag primers, starline brass and a seating depth of .560in. The max load at just under 60K psi was 36 grain H110. Sorry I’m 7 years late but hopefully it’s useful.
