Rl 26& 260 rem ? QL request?

[den]

anybody doing this I cant find much data for this combo I am trying to get the best data I can for a 260 rem load with a 143 eld x bullet at 2.852 oal, priv part reformed 1x fired 7-08 brass with fed large rifle match and a 24 in barrel, about all I could find was a little on a 155 cauterucio and a 139 scenar that will likely get me started but thought I would ask anyway, thanks for any help
