I've had good results with IMR-7828ssc and 105 VLDs.
Found the particulars...
1-8" twist Pac-Nor .243 and Berger 105 VLDs.
Of the several powder/primer combos I tried I found the accuracy I was looking for with IMR-7828ssc @ 43grs, CCI-BR2s and Lapus brass.
My records show the average velocity to be 3002 fps with an E.S. of 21.0 and an S.D. of 8.0. (CED Millennium)
Gentlemen, when the enemy is committed to a mistake we must not interrupt him too soon.
