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.
