[QUOTE="Muddyboots, post: 1880985, member: 63925"] RL26 - 0.020 off lands, G1 Sendero 26" clean barrel no brake Had done a previous ladder up to 74.0 so I started at 74.0 to see where the flat spot or pressure would occur. Both at pretty much same load. 74.0 = 2969 74.5 = chrono did not read for whatever reason - no sign of pressure on brass, bolt lift normal 75.0 = 3030 75.5 = 3074 76.0 = 3108 76.5 = 3108 77.0 = 3100 - slight ejector mark, primer rounded edges, bolt lift normal Stopped since I do not like to push brass into ejector marks etc. My plan is to reshoot at 76.0 to verify and run some at 100 yards in backyard which is all I have to work with right now. I will post up if load verifies at ~3100 or not. What is interesting to me is I am getting much higher velocities of the 180-190 with RL26 than I am with 200 gr bullets. My RL26 load for the 200AB is maybe 50 fps faster than with RL22. [/QUOTE]
