Re: 338 Lapua velocities
Readers beware, the load data below should not be duplicated, please start 3 grains low and work your way up.
Here's the data:
Reloader 25
89.8 grains 2903 fps
90 grains 2897 fps
90.2 grains 2898 fps
90.4 grains 2903 fps
90.6 grains 2911 fps
90.8 grains 2918 fps
91 grains 2906 fps
All loads with REL had "sticky" bolt lift and prominant ejectore marks and cratered primers, but accuracy and velocity spread were fantastic. I am going to test 88-90 grains to lower pressure signs. If I were to stay at these loads I will probably blow a primer soon.
Retumbo
92 2746
92.3 2782
92.7 2793 Slighty sticky bolt
93 2819 Slightly sticky bolt
93.2 2798 Moderately sticky bolt
93.4 2792 Moderately sticky bolt
93.6 2814 Sticky bolt
93.8 2827 Sticky bolt
94 2812 Sticky bolt
The Retumbo grouped really really well too, I didn't have a very good rest when I was shooting the Retumbo so the group was a bit larger than with the REL 25, I am sure with a good rest the groups would have been almost identical to the smaller groups from the REL 25.
