There is online loading data for Vihtavuori in 6.5 Grendel. They have data for 123 grain Scenar then jump to 139 grain Scenar. The max load of N135 with 123 grain bullet is 27.0 grains. The max load with the 139 grain Scenar is 23.9 grains. I have used Viht N133 & N135 but only with lighter bullets. I was at Grafs and I bought a pound of each because there was a shortage of powder.
To my recollection I dont remember loading any bullets heavier than 107 grain SMK. I used most of the N133 & N135 in 5.56/223. I really think the N140, N530 or N540 are better powders for 130 grain bullets in 6.5 Grendel. There is a member from Sweden who has tested the Viht powders extensively in a bolt action 6.5 Grendel.
I dont have any load data for N135 with 129-130 grain bullets. I personally liked the N133 & N135 better in 5.56/223 because I couldnt get as much velocity in the 6.5 Grendel with bullets heavier than 107 grains as my other powders.
I just checked Vihtavuori web site and they now list a 136 grain Scenar so using that data you should be able to find a load for 130 grain bullets.
