I loaded some RL26 using 145gr Speer #1628 BT WLR primers and Win cases at 2.780 OAL I got 2880 FPS for 5 shot..

My RL17 did exactly the same 2880 145 Gr Speer Win case 2.780 OAL SD was 10.8 Produced much better group than the RL26.

Tried RL16 with same load as above, everthing the same but got 2829 FPS for 5 shots SD was 8.8 slightly better group than RL17

I have some more loaded with WLRM to shoot tomorrow, plus a load of PP4000mr.
