My QL doesnt have the 136gr but the 139gr it has 90grs of US 869 as max at just a little over 3200ft/sec. I will bump the load up a little bit and see what I have. I know in the 260 45 grs of RL 17 drives the 123gr Scenar at 3050 and the 120 Nosler Ballistic Tip at 3120 with 45grs of RL 17. I have learned that QL is a guide to start and thats it. I personally never find it right on.
