 I have been loading with 3 different powders, IMR-3031- IMR 4198-& VVN-133.
  For all 3 powders i loaded 10 rds. of each powder. 5 rds. w/ lubed and 5rds w/ PC'd cast bullets of the same weight (.214-.215gn.)
  All rds. shot at 25yds over my chono. (till it quit due to low batt).

  IMR-4198 22.9gn-5rds.lubed HI 1463--LO 1410.
    ''      ''      ''         ''    PC'd    HI 1382--LO 1337.

   VVN-133 28.5gn- "     lubed HI 1549--LO 1511.
      "            "         "     PC'd  HI  1415--LO (chrono def)

   IMR-3031 26.8gn  "     lubed HI 1389--LO 1368.
      "             "         "     PC'd  HI  CHRONO DIED

   At 25yds i was able to shoot 3/4" groups and less , all rds seemed to be very accurate (25yds?).
What i was noticing was the FPS difference between the lubed & PCd and all rds. were sized to .406 for my rifle.

  NOTE# First,  i fired 4 rds.(across the chorno) i had loaded back on 5-02-24, w/ 22.9gns. of IMR 4198 as fouler shots and they all were in the upper 1580- 1600 fps range .

I was well pleased w/ the accuracy of all 3 powders and believe i will move out to 50yds and see how that goes, Temp was early morn and at 80 degrees. Your millage may very.

  coffee's ready,  Hootmix

Great report! Not sure why you started a thread for it tho, when there is a sticky exclusively for it.

I thought I was wrong once, but I was mistaken.
